The add() method in the XYSeries class sorts by x position, so you might want to subclass it to override that behaviour. "XYChartEntity"s give you the dataset, series and item which was selected. So you could store any metadata in your dataset (or in a separate list). Or you could subclass the rende...

I don't know about the legend (I've never needed to use a legend in my charts), but everything else you've mentioned is possible.

I don't really understand what you want with the tooltips, but I hope this helps with the JScrollPane-like behaviour:

Following up my own message, in case someone's interested in this... I haven't submitted my patches yet, but I have had quite a bit of success: Rendering 10 years of day data for MSFT on NASDAQ (around 2800 data items) simultaneously as candlesticks, bars, and two lines (in a combination of overlaid...
