John,
You are correct about the way contour handles masked data, and I agree
that it is ugly; unfortunately, it is inherent in the routine we are
using. You could reduce but not eliminate the problem by interpolating
to a finer grid.
The routine we are using, which came from the gist package,
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
