[Matplotlib-users] jagged edges on masked contour plots

[John P. <joh...@st...>]

Hi all

I have an application requiring that I do contour plots for masked data.
At the edge of my contour plots, I'm getting fragmented contours due to
missing points on the corner of a cell in my grid.

Is there any way that the contour drawing code can be set up so that it
plots contours even if a cell in the grid only has data on two sides?

I suspect that the rule for contour plots is that no contours are shown
if *any* of the point on the four corners are missing.

There is an example with the jagged edge shown in the attached image.

Cheers
JP
