Norm

Norm(norm, *args, **kwargs)[source]

Return an arbitrary Normalize instance. See this tutorial for an introduction to matplotlib normalizers.

Parameters:

norm (str or Normalize) – The normalizer specification. If a Normalize instance already, a copy.copy of the instance is returned. Otherwise, norm should be a string corresponding to one of the “registered” colormap normalizers (see below table).

If norm is a list or tuple and the first element is a “registered” normalizer name, subsequent elements are passed to the normalizer class as positional arguments.

Key(s)	Class
`'null'`, `'none'`	`NoNorm`
`'diverging'`, `'div'`	`DivergingNorm`
`'segmented'`, `'segments'`	`SegmentedNorm`
`'linear'`	`Normalize`
`'log'`	`LogNorm`
`'power'`	`PowerNorm`
`'symlog'`	`SymLogNorm`

Other Parameters:

*args, **kwargs – Passed to the Normalize initializer.

Returns:

matplotlib.colors.Normalize – A Normalize instance.
