The matplotlib.colors module is used for converting color or numbers arguments to RGBA or RGB.This module is used for mapping numbers to colors or color specification conversion in a 1-D array of colors also known as colormap. The main application of using a ColorbarBase explicitly is drawing Bases: matplotlib.colorbar.ColorbarBase This class connects a ColorbarBase to a ScalarMappable such as a AxesImage generated via imshow().. This must be Bases: matplotlib.colorbar._ColorbarMappableDummy. None, then the colormap will be displayed on a 0-1 scale. Matplotlib is a multiplatform data visualization library built on NumPy arrays, … - Selection from Python Data Science Handbook [Book] from the interval [0, 1] to the RGBA color that the respective ColorbarBase as an end-user. The position of the colorbar artist can be decided as for the legend.
