[DOC] Undocumented behavior in streamplot #13974
Description
The docstring of ax.streamplot (“only”) states
x, y : 1d arrays
an evenly spaced grid.
but looking at the actual code in the master branch (through the interface on GitHub website), it seems that a bit more of processing is involved (through the class matplotlib.streamplot.Grid) in order to also allow at least one special case of 2d-arrays for X and Y.
Expected behavior: such special casing being made explicite in the docstring.

It seems that
Gridobjects only work with 2D arrays created as innp.meshgrid(x,y, indexing="xy"), and not as innp.meshgrid(x,y, indexing="ij"). Is there a specific reason for this? I, personally, have always preferred the second way to deal with 2D (or ND) arrays.jklymak commentedon Sep 2, 2021
Because that is how all our input arrays are provided.
