Writing Image Map information

[Guest]

Hi all,

I have been trying to find the way to customize OverLib tooltip text and href information using JFreeChart

like below
<AREA SHAPE="rect" COORDS="167,423,180,437" alt="" href="myLink.html" onmouseover="return overlib('my tooltip text');" onmouseout="return nd();">

I have gone through many articles and jfreechart docs on (ChartRenderingInfo, ChartUtilities.writeImageMap etc.) but haven't been able to find a way so far.

Any help with this will be greatly appreciated.

The URL is generated by a class that implements the XYURLGenerator interface - you can write your own custom class and install it with the renderer using setURLGenerator().

Exactly the same approach is used for the tooltip text - see the XYToolTipGenerator interface and the setToolTipGenerator() method in the renderer.

Thanks Dave, That was very helpful. It works now.

Hi,

Can someone please tell me how to set the URL link based on series in a Stacked area chart. I tried with

renderer.setSeriesItemURLGenerator()
renderer.setSeriesToolTipGenerator()

but no luck.
