midpointnorm

midpointnorm(vcenter=0, vmin=None, vmax=None)

Alias to Matplotlib’s TwoSlopeNorm. Used to place the center of the colormap somewhere other than the center of the data.

Parameters:

• vcenter (float) – the center of the colormap (0 by default)

• vmin (float) – the minimum of the colormap

• vmax (float) – the maximum of the colormap

Example:

data = pl.rand(10,10) - 0.2
pl.pcolor(data, cmap='bi', norm=sc.midpointnorm())

New in version 1.2.0.
