[Matplotlib-devel] GSoC 2017: Layout Manager

Fri Mar 31 13:47:52 EDT 2017

ScalarMappables takes in an array of scalar values and returns RGBA values
relevant to each scalar. This is what I thought. Is this correct?

And by different types of scalarMappables, do you mean the different class
objects in colormaps, pyploy, etc.?

With Regards
