Tooltips are out of order when x is duplicate

[Robert Fearn]

Hi,
When I add tooltips to a dataseries where the X values are the same, the tooltips are all out of order. If I swap the X and Y so it has duplicate Y values it works fine.
Any ideas why the tooltips gets mixed up for duplicate X values.

I have attached the code to illustrate:

Cheers,
Rob.

Hi Robert,

The problem is in the XYSeries class, which doesn't preserve the add order of duplicate items. But the CustomXYToolTipGenerator requires the order to be preserved, so it is a mismatch between these two classes. I've added it as BUG 644689 on SourceForge so I don't forget about it.
