I am trying to make subplots of small images of data and I am finding it completely impossible to adjust the cmap/vmin/vmax for any of these images. No matter what I can't figure out how to change the colour map and the limits, I don't have any idea what I'm doing wrong.
Cheers!!
You are using the colorbar in a funny way. Try to do something like:
im = axarr[0,0].imshow(...)
followed by:
colorbar(im)
What it does, is to take the created image and build the colorbar on top of it.
