smpl.plot.Normalize

class smpl.plot.Normalize(vmin=None, vmax=None, clip=False)

Bases: object

A class which, when called, linearly normalizes data into the [0.0, 1.0] interval.

__init__(vmin=None, vmax=None, clip=False)

Parameters

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., __call__(A) calls autoscale_None(A).

clipbool, default: False

If True values falling outside the range [vmin, vmax], are mapped to 0 or 1, whichever is closer, and masked values are set to 1. If False masked 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 clip=False.

Notes

Returns 0 if vmin == vmax.

Methods

__init__([vmin, vmax, clip])	Parameters vmin, vmax float 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., __call__(A) calls autoscale_None(A).
autoscale(A)	Set vmin, vmax to min, max of A.
autoscale_None(A)	If vmin or vmax are not set, use the min/max of A to set them.
inverse(value)
process_value(value)	Homogenize the input value for easy and efficient normalization.
scaled()	Return whether vmin and vmax are set.

Attributes

clip
vmax
vmin

autoscale(A)

Set vmin, vmax to min, max of A.

autoscale_None(A)

If vmin or vmax are not set, use the min/max of A to set them.

static process_value(value)

Homogenize the input value for easy and efficient normalization.

value can be a scalar or sequence.

Returns

resultmasked array

Masked array with the same shape as value.

is_scalarbool

Whether value is a scalar.

Notes

Float dtypes are preserved; integer types with two bytes or smaller are converted to np.float32, and larger types are converted to np.float64. Preserving float32 when possible, and using in-place operations, greatly improves speed for large arrays.

scaled()

Return whether vmin and vmax are set.
