This is a line + at the cursor location with a readout of data points at the line location + which are displayed in the chart legend. +* Changed cursor tooltip format string. Now one format string is used for + entire tooltip. +* Added mechanisms to specify plot size when plot target is hidden or plot + height/width otherwise cannot be determined from markup. +* Added $.jqplot.config object to specify jqplot wide configuration options. + These include enablePlugins to globally set the default plugin state on/off + and defaultHeight/defaultWidth to specify default plot height/width. +* Added fillToZero option which forces filled charts to fill to zero as opposed + to axis minimum. Thus negative filled bar/line values will fill upwards to + zero axis value. +* Added option to disable stacking on individual lines. +* Changed targetId property of the plot object so it now includes a "#" before + the id string. +* Improved tick and body sizing of Open Hi Low Close and candlestick charts. +* Removed lots of web site related files from the repository. This means that, + if working from the sources, user's won't be able to build the jqplot web + site and the docs/tests that are hosted on that site. The minified and + compressed distribution packages will build fine. +* Lots of examples were added to a separate examples directory to better show + functionality of jqPlot for local testing with the distribution. +* Many various bug fixes and other minor enhancements. + + +0.9.4: + +* Implemented axis labels. Labels can be rendered in div tags or as canvas + elements supporting rotated text. +* Improved rotated axis label positioning so labels will start or end at a + tick position. +* Fixed bug where an empty data series would hang plot rendering. +* completed issue #66 for misc. improvements to documentation. +* Fixed issue #64 where the same ID's were assigned to cursor and highlighter + elements. +* Added option to legend to encode special HTML characters. +* Fixed undesirable behavior where point labels for points off the plot + were being rendered. +* Added edgeTolerance option to point label renderer to control rendering of + labels near plot edges. + + +0.9.3: + +* Preliminary support for axis labels. Currently rendered into DIV tags, + so no rotated label support. This feature is currently experimental. +* Fixed bug #52, needed space in tick div tag between style and class declarations + or plot failed in certain application doctypes. +* Fixed issue #54, miter style line join for chart lines causing spikes at steep + changes in slope. Changed miter style to round. +* Added examples for new autoscaling algorithm. +* Fixed bug #57, category axis labels disappear on redraw() +* Improved algorithm which controlled maximum number of labels that would display + on a category axis. +* Fixed bug #45 where null values causing errors in plotData and gridData. +* Fixed issue #60 where seriesColors option was not working. + + +0.9.2: + +* Fixed bug #45 where a plot could crash if series had different numbers of points. +* Fixed issue #50, added option to turn off sorting of series data. +* Fixed issue #31, implemented a better axis autoscaling algorithm and added an autoscale option. + +0.9.1: + +* Fixed bug #40, when axis pad, padMax, padMin set to 0, graph would fail to render. +* Fixed bug #41 where pie and bar charts not rendered correctly on redraw(). +* Fixed bug #11, filled stacked line plots not rendering correctly in IE. +* Fixed bug #42 where stacked charts not rendering with string date axis ticks. +* Fixed bug in redraw() method where axes ticks were not reset. +* Fixed "jqplotPreRedrawEvent" that should have been named "jqplotPostRedraw" event. + +0.9.0: + +* Added Open Hi Low Close charts, Candlestick charts and Hi Low Close charts. +* Added support for arbitrary labels on the data points. +* Enhanced highlighter plugin to allow custom formatting control of entire tooltip. +* Enhanced highlighter to support multiple y values in a data point. +* Fixed bug #38 where series with a single point with a negative value would fail. +* Improvements to examples to show what plugins to include. +* Expanded documentation for some of the plugins. + +0.8.5: + +* Added zooming ability with double click or single click options to reset zoom. +* Modified default tick spacing algorithm for date axes to give more space to ticks. +* Fixed bug #2 where tickInterval wasn't working properly. +* Added neighborThreshold option to control how close mouse must be to + point to trigger neighbor detection. +* Added double click event handler on plot. + +0.8.0: + +* Support for up to 9 y axes. +* Added option to control padding at max/min bounds of axes separately. +* Closed issue #21, added options to control grid line color and width. +* Closed issue #20, added options to filled line charts to stoke above + fill and customize fill color and transparency. +* Improved structure of on line documentation to make usage and options + docs default. +* Added much documentation on options and css styling. + +0.7.1: + +* Bug fix release +* Fixed bug #6, missing semi-colons messing up some javascript compressors. +* Fixed bug #13 where 2D ticks array of [values, labels] would fail to + renderer with DateAxisRenderer. +* Fixes bug #16 where pie renderer overwriting options for all plot types + and crashing non pie plots. +* Fixes bug #17 constrainTo dragable option mispelled as "contstrainTo". + Fixed dragable color issue when used with trend lines. + +0.7.0: + +* Pie chart support +* Enabled tooltipLocation option in highlighter. +* Highlighter Tooltip will account for mark size and highlight size when + positioning itself. +* Added ability to show just x, y or both axes in highlighter tooltip. +* Added customization of separator between axes values in highlighter tooltip. +* Modified how shadows are drawn for lines, bars and markers. Now drawn first, + so they are always behind the object. +* Adjustments to shadow parameters on lines to account for new shadow positioning. +* Added a ColorGenerator class to robustly return next available color + for a plot with wrap around to first color at end. +* Udates to docs about css file. +* Fixed bug with String x values in series and IE error on sorting (Category Axis). +* Added cursor changes in dragable plugin when cursor near dragable point. + +0.6.6b: + +* Added excanvas.js and excanvas.min.js to compressed distributions. +* Added example/test html pages I had locally into repository and to + compressed distributions. + +0.6.6a: + +* Removed absolute positioning from dom element and put back into css file. +* Duplicate of 0.6.6 with a suffix to unambiguously differentiate between + previously posted 0.6.6 release. + +0.6.6: + +* Fixed bug #5, trend line plugin failing when no trend line options specified. +* Added absolute position css spec to axis tick dom element. +* Enhancement to category axes, more intuitive handling of series with + missing data values. + +0.6.5: + +* Fixed bug #4, series of unequal data length not rendering correctly. + This is a bugfix release only. + +0.6.4: + +* Fixed bug (issue #1 in tracker) where flat line data series (all x and/or y + values are euqal) or single value data series would crash. + +0.6.3: + +* Support for stacked line (a.k.a. area) and stacked bar (horizontal and + vertical) charts. +* Refactored barRenderer to use default shape and shadow renderers. +* Added info (contacts & support information) page to web site. + +0.6.2: + +* This is a minor upgrade to docs and build only. No functionality has changed. +* Ant build script generates entire site, examples, tests and distribution. +* Improvements to documentation. + +0.6.1: + +* New sprintf implementation from Ash Searle that implements %g. +* Fix to sprintf e/f formats. +* Created new format specifier, %p and %P to preserve significance. +* Modified p/P format to better display larger numbers. +* Fixed and simplified significant digits calculation for sprintf. +* Added option to have cursor tooltip follow the mouse or not. +* Added options to change size of highlight. +* Updates to handle dates like '6-May-09'. +* Mods to improve look of web site. +* Updates to documentation. +* Added license and copyright statement to source files. + +0.6.0: + +* Added rotated text support. Uses native canvas text functionality in + browsers that support it or draws text on canvas with Hershey font +* metrics for non-supporting browsers. +* Removed lots of lint in js code. +* Moved tick css from js code into css file. +* Fix to tick positioning css. y axis ticks were positioned to wrong side of axis div. +* Re-factored axis tick renderer instantiation into the axes renderers themselves. + + +For changes prior to 0.6.0 release, please see change log at http://bitbucket.org/cleonello/jqplot/changesets/

By contrast, the GNU General Public +License is intended to guarantee your freedom to share and change free +software--to make sure the software is free for all its users. This +General Public License applies to most of the Free Software +Foundation's software and to any other program whose authors commit to +using it. (Some other Free Software Foundation software is covered by +the GNU Lesser General Public License instead.) You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +this service if you wish), that you receive source code or can get it +if you want it, that you can change the software or use pieces of it +in new free programs; and that you know you can do these things. + + To protect your rights, we need to make restrictions that forbid +anyone to deny you these rights or to ask you to surrender the rights. +These restrictions translate to certain responsibilities for you if you +distribute copies of the software, or if you modify it. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must give the recipients all the rights that +you have. You must make sure that they, too, receive or can get the +source code. And you must show them these terms so they know their +rights. + + We protect your rights with two steps: (1) copyright the software, and +(2) offer you this license which gives you legal permission to copy, +distribute and/or modify the software. + + Also, for each author's protection and ours, we want to make certain +that everyone understands that there is no warranty for this free +software. If the software is modified by someone else and passed on, we +want its recipients to know that what they have is not the original, so +that any problems introduced by others will not reflect on the original +authors' reputations. + + Finally, any free program is threatened constantly by software +patents. We wish to avoid the danger that redistributors of a free +program will individually obtain patent licenses, in effect making the +program proprietary. To prevent this, we have made it clear that any +patent must be licensed for everyone's free use or not licensed at all. + + The precise terms and conditions for copying, distribution and +modification follow. + + GNU GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License applies to any program or other work which contains +a notice placed by the copyright holder saying it may be distributed +under the terms of this General Public License. The "Program", below, +refers to any such program or work, and a "work based on the Program" +means either the Program or any derivative work under copyright law: +that is to say, a work containing the Program or a portion of it, +either verbatim or with modifications and/or translated into another +language. (Hereinafter, translation is included without limitation in +the term "modification".) Each licensee is addressed as "you". + +Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running the Program is not restricted, and the output from the Program +is covered only if its contents constitute a work based on the +Program (independent of having been made by running the Program). +Whether that is true depends on what the Program does. + + 1. You may copy and distribute verbatim copies of the Program's +source code as you receive it, in any medium, provided that you +conspicuously and appropriately publish on each copy an appropriate +copyright notice and disclaimer of warranty; keep intact all the +notices that refer to this License and to the absence of any warranty; +and give any other recipients of the Program a copy of this License +along with the Program. + +You may charge a fee for the physical act of transferring a copy, and +you may at your option offer warranty protection in exchange for a fee. + + 2. You may modify your copy or copies of the Program or any portion +of it, thus forming a work based on the Program, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) You must cause the modified files to carry prominent notices + stating that you changed the files and the date of any change. + + b) You must cause any work that you distribute or publish, that in + whole or in part contains or is derived from the Program or any + part thereof, to be licensed as a whole at no charge to all third + parties under the terms of this License. + + c) If the modified program normally reads commands interactively + when run, you must cause it, when started running for such + interactive use in the most ordinary way, to print or display an + announcement including an appropriate copyright notice and a + notice that there is no warranty (or else, saying that you provide + a warranty) and that users may redistribute the program under + these conditions, and telling the user how to view a copy of this + License. (Exception: if the Program itself is interactive but + does not normally print such an announcement, your work based on + the Program is not required to print an announcement.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Program, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Program, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Program. + +In addition, mere aggregation of another work not based on the Program +with the Program (or with a work based on the Program) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may copy and distribute the Program (or a work based on it, +under Section 2) in object code or executable form under the terms of +Sections 1 and 2 above provided that you also do one of the following: + + a) Accompany it with the complete corresponding machine-readable + source code, which must be distributed under the terms of Sections + 1 and 2 above on a medium customarily used for software interchange; or, + + b) Accompany it with a written offer, valid for at least three + years, to give any third party, for a charge no more than your + cost of physically performing source distribution, a complete + machine-readable copy of the corresponding source code, to be + distributed under the terms of Sections 1 and 2 above on a medium + customarily used for software interchange; or, + + c) Accompany it with the information you received as to the offer + to distribute corresponding source code. (This alternative is + allowed only for noncommercial distribution and only if you + received the program in object code or executable form with such + an offer, in accord with Subsection b above.) + +The source code for a work means the preferred form of the work for +making modifications to it. For an executable work, complete source +code means all the source code for all modules it contains, plus any +associated interface definition files, plus the scripts used to +control compilation and installation of the executable. However, as a +special exception, the source code distributed need not include +anything that is normally distributed (in either source or binary +form) with the major components (compiler, kernel, and so on) of the +operating system on which the executable runs, unless that component +itself accompanies the executable. + +If distribution of executable or object code is made by offering +access to copy from a designated place, then offering equivalent +access to copy the source code from the same place counts as +distribution of the source code, even though third parties are not +compelled to copy the source along with the object code. + + 4. You may not copy, modify, sublicense, or distribute the Program +except as expressly provided under this License. Any attempt +otherwise to copy, modify, sublicense or distribute the Program is +void, and will automatically terminate your rights under this License. +However, parties who have received copies, or rights, from you under +this License will not have their licenses terminated so long as such +parties remain in full compliance. + + 5. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Program or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Program (or any work based on the +Program), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Program or works based on it. + + 6. Each time you redistribute the Program (or any work based on the +Program), the recipient automatically receives a license from the +original licensor to copy, distribute or modify the Program subject to +these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties to +this License. + + 7. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Program at all. For example, if a patent +license would not permit royalty-free redistribution of the Program by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Program. + +If any portion of this section is held invalid or unenforceable under +any particular circumstance, the balance of the section is intended to +apply and the section as a whole is intended to apply in other +circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system, which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 8. If the distribution and/or use of the Program is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Program under this License +may add an explicit geographical distribution limitation excluding +those countries, so that distribution is permitted only in or among +countries not thus excluded. In such case, this License incorporates +the limitation as if written in the body of this License. + + 9. The Free Software Foundation may publish revised and/or new versions +of the General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + +Each version is given a distinguishing version number. If the Program +specifies a version number of this License which applies to it and "any +later version", you have the option of following the terms and conditions +either of that version or of any later version published by the Free +Software Foundation. If the Program does not specify a version number of +this License, you may choose any version ever published by the Free Software +Foundation. + + 10. If you wish to incorporate parts of the Program into other free +programs whose distribution conditions are different, write to the author +to ask for permission. For software which is copyrighted by the Free +Software Foundation, write to the Free Software Foundation; we sometimes +make exceptions for this. Our decision will be guided by the two goals +of preserving the free status of all derivatives of our free software and +of promoting the sharing and reuse of software generally. + + NO WARRANTY + + 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY +FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN +OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES +PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED +OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF +MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS +TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE +PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, +REPAIR OR CORRECTION. + + 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR +REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, +INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING +OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED +TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY +YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER +PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE +POSSIBILITY OF SUCH DAMAGES.

For a listing of options available to jqPlot, +see <jqPlot Options> in the jqPlotOptions.txt file. + +The key to effectively using jqPlot is understanding jqPlot's +options. The online documentation is API documentation. While +it explains what attributes and methods various objects posses, +it doesn't explain how to use or set those attributes through +options. This tutorial will help explain that. + +Lets assume you are creating a plot +like this: + +> chart = $.jqplot('chart', dataSeries, optionsObj); + +First, note that you shouldn't try to directly set attributes on the +"chart" object (like chart.grid.shadow) after your call to $.jqplot(). +At best this won't do anything **(see below). You should pass options in via +the "optionsObj". + +the optionsObj really represents the plot object (jqPlot object, not +to be confused with the $.jqplot function which will create a jqPlot +object). Attributes you specify on that object will be merged with +attributes in the jqPlot object. The axes, legend, series, etc. are +attributes on the jqPlot object. The jqPlot/optionsObj object looks +something like (only some attributes shown): + +> jqPlot-| +> |-seriesColors +> |-textColor +> |-fontFamily +> |-fontSize +> |-stackSeries +> |-series(Array)-| +> | |-Series1-| +> | | |-lineWidth +> | | |-shadow +> | | |-showLine +> | | |-showMarker +> | | |-color +> | |-Series2... +> | |-... +> | |-SeriesN +> | +> |-grid(Object)-| +> | |-drawGridLines +> | |-background +> | |-borderColor +> | |-borderWidth +> | |-shadow +> | +> |-title(Object)-| +> | |-text +> | |-show +> | |-fontFamily +> | |-fontSize +> | |-textAlign +> | |-textColor +> | +> |-axes(Object)-| +> | |-xais-| +> | | |-min +> | | |-max +> | | |-numberTicks +> | | |-showTicks +> | | |-showTickMarks +> | | |-pad +> | +> | ... and so on + +The optionsObj should follow the same construction as if it were a +jqPlot object (with some exceptions/shortcuts I'll mention in a +moment). So generally, when you see something like +"this.drawGridLines" in the grid properties in the docs, just replace +"this" with "grid" in your options object. So it becomes +optionsObj.grid.drawGridLines. Do likewise with the other objects in +the plot, replacing "this", with the respective attribute on the plot +like "legend" or "title". Series and Axes are handled a little +different, because series is an array and axes has 4 distinct children +"xaxis", "yaxis", "x2axis" and "y2axis". + +So, to remove the shadow from the grid and change the grid border size +you would do: + +> optionObj = {grid:{shadow:false, borderWidth:9.0}}; + +To do the same as above but also make all the text in the plot red you +would do: + +> optionObj = { +> textColor:"#ff0000", +> grid:{shadow:false, borderWidth:9.0} +> } + +Here is a more deeply nested example. Say you want to specify a min +and max on your y axis and use a specific color for your second +series. That would look like: + +> optionsObj = { +> axes:{yaxis:{min:5, max:230}}, +> series:[{},{color:"#33ff66"}] +> } + +Note that series options are an array in order of the series data you +sent in to your plot. To get to the second series, you have to put an +object (even if empty) in place of the first series. + +There is a handy shortcut to assign options to all axes or all series +at one go. Use axesDefaults and seriesDefaults. So, if you wanted +both x and y axes to start at 0 and you wanted all series to not show +markers, you could do: + +> optionsObj = {axesDefaults:{min:0}, seriesDefaults:{showMarker:false}} + +Another shortcut is for the plot title. Normally, you would assign +options to the title as an object. If you specify a title option as a +string, it will assign that to the title.text property automatically. +So these two are equivalent: + +> optionsObj = {title:{text:"My Plot"}} + +and + +> optionsObj = {title:"My Plot"} + +Where things need more explaination is with renderers, plugins and +their options. Briefly, what's renderer, what's a plugin. + +A renderer is an object that is used to draw something and gets +attached to an existing object in the plot in order to draw it. A +plugin does more than just provide drawing functionality to an +object. It will do more like calculate a trend line, change the +cursor, provide event driven functionality, etc. I consider renderers +plugins, but plugins don't have to be renderers. + +So, how do you use renderers, plugins, and specify their options? +Some common renderes are for bar charts and category axes. If you +want to render your series as a bar chart with each set of bars +showing up in a category on the x axis, you do: + +> optionsObj = { +> seriesDefaults:{renderer:$.jqplot.BarRenderer}, +> axes:{xaxis:{renderer:$.jqplot.CategoryAxisRenderer}} +> } + +This replaces the default renderer used for all series in the plot +with a bar renderer and the x axis default renderer (but not any other +axis) with a category renderer. + +Now, how would I assign options to those renderers? The renderer's +attributes may not be present in the pre-existing jqPlot object, they +may be specific to the renderer. This is done through the +"rendererOptions" option on the appropriate object. So, if I wanted my +bars to be 25 pixels wide, I would do: + + +> optionsObj = { +> seriesDefaults:{ +> renderer:$.jqplot.BarRenderer}, +> rendererOptions:{ +> barWidth:25 +> }, +> axes:{xaxis:{renderer:$.jqplot.CategoryAxisRenderer}} +> } + +Again, this is using the "seriesDefaults" option, which will apply +options to all series in the plot. You could do the same on any +particular series in the plot through the "series" options array. + +Plugins are free to add their own options. For example, the +highlighter plugin has it's own set of options that are unique to it. +As a result, it responds to options placed in the "highlighter" +attribute of your options object. So, if I wanted to change the +highlighter tooltip to fade in and out slowly and be positioned +directly above the point I'm highlighting: + +> optionsObj = { +> highlighter:{tooltipFadeSpeed:'slow', tooltipLocation:'n'} +> } + +Other plugins, like dragable and trendlines, add their options in with +the series. This is because both of those plugins can have different +options for different series in the plot. So, if you wanted to specify the +color of the dragable and constrain it to drag only on the x axis as well +as specify the color of the trend line you could do: + +> series:[{ +> dragable: { +> color: '#ff3366', +> constrainTo: 'x' +> }, +> trendline: { +> color: '#cccccc' +> } +> }] + +This would apply those options to the first series only. If you had 2 series +and wanted to turn off dragging and trend lines on the second series, you could do: + +> series:[{ +> dragable: { +> color: '#ff3366', +> constrainTo: 'x' +> }, +> trendline: { +> color: '#cccccc' +> } +> }, { +> isDragable: false, +> trendline:{ +> show: false +> } +> }] + +Note, series dragability is turned off with the "isDragable" option directly on +the series itself, not with a suboption of "dragable". This may be improved +in the future. + +I hope this is helpful. +A few key points to remember: + +- When you see "this" in the api docs, you generally replace it with +the name of the object (in lowercase) you are looking at in your +options object. +- seriesDefaults and axesDefaults are convenient shortcuts. +- to assign options to a renderer, generally use the "rendererOptions" +- plugins may add their own options attribute, like "highlighter" or +"cursor". + +** Note: you can set attributes after the plot is created (like +plot.grid.shadow = false), but you'll have to issue the appropriate +calls to possibly reinitialize and redraw the plot. jqPlot can +definitely handle this to change the plot after creation (this is how +the dragable plugin updates the plot data and the trend line plugin +recomputes itself when data changes). This hasn't been documented +yet, however.

These plots are shown as static images. +Many more examples of dynamically rendered plots can be seen on the test and examples pages here: <../../tests/>. + +Include the Files: + +jqPlot requires jQuery (1.4+ required for certain features). jQuery 1.4.4 is included in the distribution. +To use jqPlot include jquery, the jqPlot jQuery plugin, jqPlot css file and optionally the excanvas +script for IE support in your web page. Note, excanvas is required only for IE versions below 9. IE 9 includes +native support for the canvas element and does not require excanvas: + +> <!--[if lt IE 9]><script language="javascript" type="text/javascript" src="excanvas.js"></script><![endif]--> +> <script language="javascript" type="text/javascript" src="jquery-1.4.4.min.js"></script> +> <script language="javascript" type="text/javascript" src="jquery.jqplot.min.js"></script> +> <link rel="stylesheet" type="text/css" href="jquery.jqplot.css" /> + +Add a plot container: + +Add a container (target) to your web page where you want your plot to show up. +Be sure to give your target a width and a height: + +> <div id="chartdiv" style="height:400px;width:300px; "></div> + +Create a plot: + +Then, create the actual plot by calling the +$.jqplot plugin with the id of your target and some data: + +> $.jqplot('chartdiv', [[[1, 2],[3,5.12],[5,13.1],[7,33.6],[9,85.9],[11,219.9]]]); + +Which will produce a +chart like: + +(see images/basicline.png) + +Plot Options: + +You can customize the plot by passing options to the $.jqplot function. Options are described in +<jqPlot Options> in the jqPlotOptions.txt file. An example of options usage: + +> $.jqplot('chartdiv', [[[1, 2],[3,5.12],[5,13.1],[7,33.6],[9,85.9],[11,219.9]]], +> { title:'Exponential Line', +> axes:{yaxis:{min:-10, max:240}}, +> series:[{color:'#5FAB78'}] +> }); + +Which will produce +a plot like: + +(see images/basicoptions.png) + +Using Plugins: + +You can use jqPlot plugins (that is, plugins to the jqPlot plugin) by including them in your html +after you include the jqPlot plugin. Here is how to include the log axis plugin: + +> <link rel="stylesheet" type="text/css" href="jquery.jqplot.css" /> +> <!--[if IE]><script language="javascript" type="text/javascript" src="excanvas.js"></script><![endif]--> +> <script language="javascript" type="text/javascript" src="jquery-1.4.4.min.js"></script> +> <script language="javascript" type="text/javascript" src="jquery.jqplot.min.js"></script> +> <script language="javascript" type="text/javascript" src="jqplot.logAxisRenderer.js"></script> + +Important note: For jqplot builds r529 and above (0.9.7r529 and higher), you must explicitly +enable plugins via either the { show: true } plugin option to the plot or by using +the $.jqplot.config.enablePlugins = true; config options set on the page before plot creation. +Only plugins that can be immediately active upon loading are affected. This includes +non-renderer plugins like cursor, dragable, highlighter, and trendline. + +Here is a the same $.jqplot call +but with a log y axis: + +> $.jqplot('chartdiv', [[[1, 2],[3,5.12],[5,13.1],[7,33.6],[9,85.9],[11,219.9]]], +> { title:'Exponential Line', +> axes:{yaxis:{renderer: $.jqplot.LogAxisRenderer}}, +> series:[{color:'#5FAB78'}] +> }); + +Which produces +a plot like: + +(see images/basiclogaxis.png) + +You can further customize with options specific +to the log axis plugin: + +> $.jqplot('chartdiv', [[[1, 2],[3,5.12],[5,13.1],[7,33.6],[9,85.9],[11,219.9]]], +> { title:'Exponential Line', +> axes:{yaxis:{renderer: $.jqplot.LogAxisRenderer, tickDistribution:'power'}}, +> series:[{color:'#5FAB78'}] +> }); + +Which makes a +plot like: + +(see images/basiclogoptions.png) + +For a full list of options, see <jqPlot Options> in the jqPlotOptions.txt file. + +You can add as many plugins as you wish. Order is generally not important. +Some plugins, like the highlighter plugin which highlights data points near the +mouse, don't need any extra options or setup to function. Highlighter does have +additional options which the user can set. + +Other plugins, the barRenderer for example, provide functionality the must be specified +in the chart options object. To render a series as a bar graph with the bar renderer, +you would first include the plugin after jqPlot: + +> <script language="javascript" type="text/javascript" src="plugins/jqplot.barRenderer.min.js"></script> + +Then you would create +a chart like: + +> $.jqplot('chartdiv', [[34.53, 56.32, 25.1, 18.6]], {series:[{renderer:$.jqplot.BarRenderer}]}); + +Here the default LineRenderer is replaced by a BarRenderer to generate a bar graph for the first (an only) series.
