Colorbar - change color of a specific value
5 views (last 30 days)
I am displaying a map of temperature using contourf and a colorbar (see below). All low temperatures that are not exact are set to Nan and i've set the background to black. The max temperature is not exact either because my sensor is saturated. So I would like to display saturated temperature to another color (like white for example), without having it displayed on the colorbar.
I've isolated max values of spots in an array, but how can I say that all my pixels equal to this value = a specific color? And is it possible not to have this color on the colorbar?
contourf(heure_num, distance, spots, 100,'LineColor', 'none');
c = colorbar;
set(gca, 'fontsize', 14);
set(gca, 'ydir', 'reverse');
Thanks for helping me and sorry for my english.
EDIT : while I was searching I run into this :
cm = colormap;
cm(1, :) = [1 1 1];
This seems to turn the lower values of the colormap into black? How do I do that for the max value and in white please?
