edges¶
- edges(z, axis=- 1)[source]¶
Calculate the approximate “edge” values along an axis given “center” values. This is used internally to calculate graticule edges when you supply centers to
pcolor
orpcolormesh
. It is also used to calculate colormap level boundaries when you supply centers to plotting methods wrapped byapply_cmap
.- Parameters
z (array-like) – Array of any shape or size.
axis (int, optional) – The axis along which “edges” are calculated. The size of this axis will be increased by one.
- Returns
ndarray
– Array of “edge” coordinates.
