X Title: Added the from_levels_and_colors function. by pelson · Pull Request #2050 · matplotlib/matplotlib

Description: This PR adds a function which simplifies the construction of a cmap and norm for discrete levels with specific colours. The interface is intentionally similar to the contourf levels and colors arguments - though a little stricter in the fact that the correct number of colors for levels is required. This has come up a couple of times with my colleagues and I always end up having to write a chunk of test code to make sure I've done it right. This function generally makes this easier - and will hopefully make doing quantized pcolormesh's less error prone.
