stats graphics class ?

[rekam]

Hello !

 

Is there an existing class which can draw statistics graphics , just like you can do in Excel ?

The Graphics object has a bunch of methods for drawing shapes, a pie being one of them.

Thanks Machaira, I'm trying that. But I have problem with the paint method. When I draw inside the Form itself, I use the onPaint event to repaint the graph. Everything is okay.

 

But when I draw inside a pictureBox, the only intresting method is the paint method. But it's not very good. Some parts of the graph don't repaint...hum well, I'm searching a way to avoid that, but until now, I didn't find anything
