It can be edited (see inline comment) to give you exactly the result you want, but that the colours of the bar then still correspond to the colours in the graph, is only due to the specific colour map that's used (I think): Always correct solution that can't handle values outside [vmin,vmax]: Thanks for contributing an answer to Stack Overflow! Provides a new artist for matplotlib to display a colorbar, instead of an axis as it is the default in matplotlib.
