+      Call this whenever the mappable is changed to notify all the
+      callbackSM listeners to the 'changed' signal.
+
+   .. method::  set_array(A)
+
+      Set the value array from array-like *A*.

+          **A** : array-like or None
+              The values that are mapped to colors.

+              The base class `.ScalarMappable` does not make any assumptions on
+              the dimensionality and shape of the value array *A*.

+          **vmin, vmax** : float
+              The limits.
