(This is a different question for the same project that led me to file a
bug about alpha blending in "contour" .)
I want to overlay a number of exclusion regions in a 2D parameter scan.
I generate each region with contourf in succession, like:
The problem as you might guess is that if I overlay many regions, the
white level at each new region washes out the underlying non-white
Is there a "transparent" color I can use instead of white? Or, is there
an alternative way to overlay regions that avoids this problem?
Thank you again!
