Hello,
I am required to do some contour or surface plots where the x and y axes are non-orthogonal. It might appear trivial because a non-orthogonal contour section is a part of the orthogonal coordinate system. But the problem is, for contour and surface plots with orthogonal coordinates we need a rectangular mesh. However if the mesh of datapoints are not rectangle we cannot use the contourf type functions. So a routine is required to be able to draw contours and surfaces for non-rectangular mesh (or non-orthogonal coordinate system).
Moreover the problem with not having a roitine for ternary plots (posted several times) is a special case of the aforesaid issue.
Thus I request the developers of matplotlib to develop a routine to address this problem.
Let me know your opinion at your earliest convenience.
Sincerely,
Shankha
