Hello,
I have a countourf plot with a logscale colormap using the function "set(gca,'colorscale','log')". I would like to try other options for the scale of the colormap (i.e. ln, log2, etc). I would be interested in an option similar to is provided by matplotlib: https://matplotlib.org/tutorials/colors/colormapnorms.html#sphx-glr-tutorials-colors-colormapnorms-py
How could I do this?
Thanks

I do not think there is native Matlab feature to do that. You can convert your data into your desired log function and plot it on a linear scale instead.
contourf(log2(x))
Blessings,
Spencer
