This module includes functions and classes for color specification conversions, and for mapping numbers to colors in a 1-D array of colors called a colormap. Mapping data onto colors using a colormap typically involves two steps: a data array is first mapped onto the range using a subclass of Normalize , then this number is mapped to a color using a subclass of Colormap. Two subclasses of Colormap provided here: LinearSegmentedColormap , which uses piecewise-linear interpolation to define colormaps, and ListedColormap , which makes a colormap from a list of colors.
