Closing and opening charts

[Gooseman]

When I create a JFreeChart to display moving data in a new ChartFrame, everything works fine. But when I close the chart and reopen it, I get duplicate points everywhere. Is there a way around this without removing the data. Do I need a listener to check if the window is closed, and act on this?

Thanks for the help!

That sounds bad. Can you send me some sample code that I can use to reproduce the problem?
