Dummy replacement for
Normalize, for the case where we want to use indices directly in a
- vmin, vmaxfloat or None
If vmin and/or vmax is not given, they are initialized from the minimum and maximum value, respectively, of the first input processed; i.e.,
- clipbool, default: False
Truevalues falling outside the range
[vmin, vmax], are mapped to 0 or 1, whichever is closer, and masked values are set to 1. If
Falsemasked values remain masked.
Clipping silently defeats the purpose of setting the over, under, and masked colors in a colormap, so it is likely to lead to surprises; therefore the default is
Returns 0 if
vmin == vmax.

Normalize value data in the
[vmin, vmax]interval into the
[0.0, 1.0]interval and return it.
