edges(Z, axis=-1)[source]

Calculate the approximate “edge” values along an arbitrary axis, given “center” values. This is used internally to calculate graticule edges when you supply centers to pcolor or pcolormesh and to calculate colormap levels when you supply centers to any method wrapped by cmap_changer.

  • Z (array-like) – Array of any shape or size. Generally, should be monotonically increasing or decreasing along axis.

  • axis (int, optional) – The axis along which “edges” are calculated. The size of this axis will be increased by one.


ndarray – Array of “edge” coordinates.
