In working on creating updating pcolor plots, I noticed that I can't create colorbars (which should be static) without first displaying an image. I have a fixed Normalize object and colormap, so I would think that the colorbar wouldn't actually need any information from the image itself.
Is there any to create a colorbar without first actually plotting an image? If not, is there any reason colorbar couldn't be modified to work using only a norm and a cmap?
