class MidpointNorm(midpoint=0, vmin=None, vmax=None, clip=None)[source]

Bases: matplotlib.colors.Normalize

Ensures a “midpoint” always lies at the central colormap color. Can be used by passing norm='midpoint' to any command accepting cmap. The default midpoint is zero.

  • midpoint (float, optional) – The midpoint, or the data value corresponding to the normalized value 0.5 – halfway down the colormap.

  • vmin, vmax, clip – The minimum and maximum data values, and the clipping setting. Passed to Normalize.

Methods Summary
