在wxPanel中绘制实时图形的最佳方法是什么？

Question

There will be approximately 400 line in each frame in 400*300 wxPanel. I used PaintDC but it performed lower than 30fps and it caused high load. Is there any alternative solution in wxPython instead of just switching PyGame?

Answer 1

You should look at the wxPython mailing list. I doubt most users will notice if the frame rate is lower than 30 fps. You should also look at matplotlib which can be integrated into wxPython. See the following:
