Colormap Normalization

Colormap Normalization¶

Objects that use colormaps by default linearly map the colors in the colormap from data values vmin to vmax. For example:

Classes

BoundaryNorm(boundaries, ncolors[, clip])	Generate a colormap index based on discrete intervals.
Colormap(name[, N])	Baseclass for all scalar to RGBA mappings.
LightSource([azdeg, altdeg, hsv_min_val, ...])	Create a light source coming from the specified azimuth and elevation.
LinearSegmentedColormap(name, segmentdata[, ...])	Colormap objects based on lookup tables using linear segments.
ListedColormap(colors[, name, N])	Colormap object generated from a list of colors.
LogNorm([vmin, vmax, clip])	Normalize a given value to the 0-1 range on a log scale
NoNorm([vmin, vmax, clip])	Dummy replacement for Normalize, for the case where we want to use indices directly in a ScalarMappable .
Normalize([vmin, vmax, clip])	A class which, when called, can normalize data into the [0.0, 1.0] interval.
PowerNorm(gamma[, vmin, vmax, clip])	Linearly map a given value to the 0-1 range and then apply a power-law normalization over that range.
SymLogNorm(linthresh[, linscale, vmin, ...])	The symmetrical logarithmic scale is logarithmic in both the positive and negative directions from the origin.
