pyensae.graphhelper._colormap.cmap_builder(name, name2=None, name3=None)

Returns a colormap object compatible with matplotlib If only parameter name is provided, it should be a known matplotlib colormap name (e.g., jet). If name2 is provided, then a new colormap is created going from the color name to the color name2 with a linear scale. Finally, if name3 is provided, a linear scaled colormap is built from color name to color name3 with the intermediate color being the name2.
