[jCharts-users] Charts again

[<pve...@ic...>]

Thanks Nathaniel, but I haven't fix the problem yet.

I'm using the code below as an example. The problem with this code is that, if
you maximize, minimize or resize the frame, the chart disappear.

I guess the problem is with the paint(Graphics) method at Charts class, I tried
overwritting that method as you said, but it didn't work. 

I don't know what to do. Please give me some advises.
