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. |
