- __call__(values, clip=True, out=None)#
Transform values using this interval.
The
vmin
andvmax
values are determined by theget_limits
method.The following transformation is then applied to the values:
\[{\rm result} = \frac{{\rm values} - v_{\rm min}} {v_{\rm max} - v_{\rm min}}\]If
clip
isTrue
(default), the result is then clipped to the [0:1] range.- Parameters:
- valuesarray_like
The input values.
- clipbool, optional
If
True
(default), values outside the [0:1] range are clipped to the [0:1] range.- out
ndarray
, optional If specified, the output values will be placed in this array (typically used for in-place calculations).
