class CenteredNorm(colors.Normalize):

def __init__(self, vcenter=0, halfrange=None, clip=False):
|
|
"""
|
|
Normalize symmetrical data around a center (0 by default).
|
|
|
|
Unlike `TwoSlopeNorm`, `CenteredNorm` applies an equal rate of change
|
|
around the center.
|
|
|
|
Useful when mapping symmetrical data around a conceptual center
|
|
e.g., data that range from -2 to 4, with 0 as the midpoint, and
|
|
with equal rates of change around that midpoint.
|
|
|
|
Parameters
|
|
----------
|
|
vcenter : float, default: 0
|
|
The data value that defines ``0.5`` in the normalization.
|
|
halfrange : float, optional
|
|
The range of data values that defines a range of ``0.5`` in the
|
|
normalization, so that *vcenter* - *halfrange* is ``0.0`` and
|
|
*vcenter* + *halfrange* is ``1.0`` in the normalization.
|
|
Defaults to the largest absolute difference to *vcenter* for
|
|
the values in the dataset.
|
|
|
|
Examples
|
|
--------
|
|
This maps data values -2 to 0.25, 0 to 0.5, and 4 to 1.0
|
|
(assuming equal rates of change above and below 0.0):
|
|
|
|
>>> import matplotlib.colors as mcolors
|
|
>>> norm = mcolors.CenteredNorm(halfrange=4.0)
|
|
>>> data = [-2., 0., 4.]
|
|
>>> norm(data)
