Is there a way to draw a curved line chart?

Post by vlaz » Fri Oct 13, 2006 6:50 pm

Instead of drawing a line chart, is there a way that I can make the line curvi-linear (e.g. a cubic spline or something like that)? How would I do it? Do I need to extend or subclass a renderer? If so, which one?

Any guidance on this would appreciated.

Thank you,
Richard

Try extending XYLineAndShapeRenderer -- maybe start by looking at the code around drawPrimaryLine() and drawItem()?
