Thank you for the suggestion. I now have the update time down to about 70 ms. When I run the code through the profiler, I see that each plot update requires a call to matplotlib.colors.Colormap.__call__, and each of these calls takes 52 ms, 48 ms of which is spent inside the function itself. This looks like it is the bulk of the delay, so if I can optimize the Colormap.__call__ function, the performance should be much improved. Unfortunately I cannot seem to get finer grained information about what exactly is taking so long inside this function. Can anyone provide any hints? Thanks, Glenn
