Hello,

I created a graph : contour color fill which represent different values on Africa. I have missing values on latitude and longitude which are ocean and cloud above Africa. So I choose the color white to represent these values. But as you can see on the screenshot of my graph, I have some missing values of cloud on Africa near the ocean and so we can not see anymore the border of the Africa along the ocean. Do you know a solution to let appear the outline of Africa and allow to distinguish the Africa with clouds of the ocean.

Thank you very much by advance,

Meryll
