I still think that wxFreeChart is the way forward for wxWidgets charting and feel sorry that I haven't had time to work on it at all :oops:

I have been working on other (non-software) projects and stumbled across GNU Radio Interestingly it offers both Qt and wxWidgets graphing options.

IMHO the wxWidgets one is better, more complete and it has a really nice 'persistence' function. Interestingly, it seems to be implemented from scratch using OpenGL and wxPython.

I am really impressed with the refresh speed, especially when averaging is applied and the waterfall graph. There are some examples here:

I have hardly used OpenGL, but I wonder if it would be interesting to offer as a backend option for wxFreeChart.
