jqPlot donut chart with legends issue - jqplot

Question

I have jqplot donut chart where I want to add chart labels in the center part. Also want to add scrolling for labels in the middle of graph. So only 1-2 labels in the center will be visible and rest will be visible when user scrolls.
Please have a look attached image. As per my knowledge, we can't add labels in the center of chart. Is there any way to do this? Appreciate your help.
My current code is as below:
<script type="text/javascript">
var _chart5_plot_properties;
_chart5_plot_properties = {
title: " ",
"seriesDefaults":{
renderer:$.jqplot.DonutRenderer,
rendererOptions:{
sliceMargin: 0,
innerDiameter: 220,
startAngle: -90,
barPadding: 0,
padding: 3,
}
},
grid: {
shadow: false,
drawBorder: false,
shadowColor: "transparent"
},
highlighter: {
show: true,
tooltipLocation: "sw",
useAxesFormatters:false
}
}
plot2 = $.jqplot("chart2", chart_data, _chart5_plot_properties);

Answer 1

I couldn't find an option for this in jqPlot.
Though, jqPlot has 8 options to position the legend, but it does not have the center option. jqPlot Legend Locations
But after tweaking it a bit, I could accomplish it using jQuery. Since we need to require jQuery to render/draw jqPlot charts, so I thought of using jQuery rather than pure Javascript.
I have used two functions defineDimensionsForLegendTable(parentContainerID, dimensions) and fixLegendsToCenter(parentContainerID)
Other important things that you should not miss out while using these functions
Make sure you include the jquery.jqplot.js, jqplot.pieRenderer.js, jqplot.donutRenderer.js, jquery.jqplot.css files (or the minified versions - .min.js)
Set placement to outsideGrid in legendOptions
legend: { show:true, placement: 'outsideGrid' }
Give a higher z-index to the legend-table
#chart2 .jqplot-table-legend{
z-index: 99999;
}

Note: If the chart does not show up in Google Chrome, try opening it in Firefox or some other browser.
Remove the console.log lines from the code ;-)
You can use Foundation or Bootstrap to beautify the scrollbar. :-)
Hope it helps :-)
