Okay, I can't find where I came up with the original solution to use imshow with custom clevs... I think it was a thread on this forum possibly, or in an example. But the point is that I recall there was some development talk about improving the handling of log data for this issue.... Does anyone have some pointers on these changes?
I guess what you would suggest is that I interpolate the data, then use pcolor to plot it? Thanks. Michael Droettboom-3 wrote: > > imshow doesn't handle logarithmic data.
