Add line, bar and pie charts to TWiki topics using jqPlot JavaScript library


<div id='chart1' style='height:280px; width: 500px;'></div>
$.jqplot ('chart1', [[3,7,9,1,4,6,8,2,5]]);

Resulting chart (if plugin is installed and enabled): %JQPLOT{"canvasTextRenderer,canvasAxisLabelRenderer"}%

More examples are found in the official jqPlot website.


jqPlot is a "pure javascript plotting" library, and this TWiki plugin bundles the package with easy setup using %JQPLOT% tag.

Since jqPlot depends on the jQuery JavaScript library, JQueryPlugin must be installed for JqPlotPlugin to work.

When a %JQPLOT% tag is present, the necessary JavaScript and CSS references are added to the <head> of the page. The %JQPLOT% tag itself is expanded into an empty string. Even if the tag happens to be used multiple times, the required references are added only once.

In order to use jqPlot plugins (for bar charts, pie charts, axis labels, etc.), the plugin names should be added to the %JQPLOT% tag.

%JQPLOT{"barRenderer, pieRenderer, categoryAxisRenderer"}%

The above will add the <script> tags to the <head> as below:

<script type="text/javascript" src=".../plugins/jqplot.barRenderer.min.js"></script>
<script type="text/javascript" src=".../plugins/jqplot.pieRenderer.min.js"></script>
<script type="text/javascript" src=".../plugins/jqplot.categoryAxisRenderer.min.js"></script>

All the common references such as jquery.jqplot.min.js (which would be added by the empty %JQPLOT%) are also added automatically.
