<p>Bubble charts represent 3 dimensional data. First, a basic bubble chart with the "bubbleGradients: true" option to specify gradient fills. Radial gradients are not supported in IE version before IE 9 and will be automatically disabled.</p>
<div id="chart1" style="height:340px; width:460px;"></div>
<pre class="code prettyprint brush: js"></pre>
<p>Data is passed in to a bubble chart as a series of [x, y, radius, <label or object>]. The optional fourth element of the data point can either be either a label string or an object having 'label' and/or 'color' properties to assign to the bubble.</p>
<p>By default, all bubbles are scaled according to the size of the plot area. The radius value in the data point will be adjusted to fit the bubbles in the chart. If the "autoscaleBubbles" option is set to false, the radius value in the data will be taken as a literal pixel value for the radius of the points.</p>
<p>Next are some basic customizations of bubble appearance with the "bubbleAlpha" and "highlightAlpha" options.</p>
<div id="chart2" style="height:340px; width:460px;"></div>
<pre class="code prettyprint brush: js"></pre>
<p>In the following example, display of a custom toolip and highlighting of a custom table legend is performed by binding to the "jqplotDataHighlight" and "jqplotDataUnhighlight" events. The custom legend table here is dynamically created with a few lines of jQuery (O.K., it could be done in one line) based on the data array of the plot.</p>
<div style="position:absolute;z-index:99;display:none;" id="tooltip1b"></div>
<table style="margin-left:auto; margin-right:auto;"><tr>
<td><div id="chart1b" style="width:460px;height:340px;"></div></td>
<td><div style="height:340px;"><table id="legend1b"><tr><th>Company</th><th>R Value</th></tr></table></div></td>
</tr></table>
