matplotlib.colors.from_levels_and_colors

matplotlib.colors. from_levels_and_colors ( levels, colors, extend='neither' ) [source]

A helper routine to generate a cmap and a norm instance which behave similar to contourf's levels and colors arguments.

Parameters:

Parameters:	levels sequence of numbers The quantization levels used to construct the `BoundaryNorm`. Value `v` is quantized to level `i` if `lev[i] <= v < lev[i+1]`. colors sequence of colors The fill color to use for each level. If extend is "neither" there must be `n_level - 1` colors. For an extend of "min" or "max" add one extra color, and for an extend of "both" add two colors. extend {'neither', 'min', 'max', 'both'}, optional The behaviour when a value falls out of range of the given levels. See `contourf` for details.
Returns:	cmap `Normalize` norm `Colormap`
