LegendItemToolTipGenerator - tooltips for legend items??

[jusepi]

Hi, I would like to put tooltips on the legend items in an XYPlot. I noticed the method:

Code: Select all

setLegendItemToolTipGenerator(XYSeriesLabelGenerator generator)

under the XYLineAndShapeRenderer object. But for some reason, it seems to do nothing. I even see print out statements that I inserted in my own custom XYSeriesLabelGenerator under the generateLabel method. So it looks like the data is there but just not getting used. Is this an unimplemented method as of 1.0.2? Is there anyone out there who has tried dealing with this? Thanks much.

It is a bug, unfortunately. The fix is in CVS, ready for the 1.0.3 release. Here is the ChangeLog entry:

Code: Select all

Thanks for the note.

What happened to LegendItemBlockContainer? It's marked as dead in CVS, but the latest version of LegendTitle still uses it. Also this means that LegendItemEntity will need to change as well right? So I assume this feature is not working as of yet...

Are you looking at the STABLE_1-0-0 branch?

ya, that's what I found on sourceforge.
But I've added the changes you mentioned and copied the LegendTitle class from CVS, and it works great. Thanks a bunch for the tips.
