I'm trying to customize a colorbar on a contoured image I am producing. I would like custom intervals with different colors between each interval. Below are a few lines of how I tried to generate such a colorbar but with no success.
contourfm(lats,lons,data,[0 25 50 75 125 150 200 300 400]);
c = colorbar;
c.Label.String = titl;
c.Limits = [minC 500];
c.Ticks = [0 25 50 75 125 150 200 300 400];
limits = c.Limits;
cInt = linspace(limits(1),limits(2),64);
cmap = flipud(jet);
Below is an example of how I am trying to make rainfall <25% of normal a yellow/orange color. I do similar iterations for 25-50% of normal, etc..
in1 = find(cInt <= 25);
nin1 = length(in1);
for i=1:nin1
cmap(in1(i),:) = [1 0 0]; %[0.9937,0.7454,0.2403];
end
This code however is not getting me the desired results.

Hi Ryan,
I understand that you want to map different data intervals to different colors. One way of doing that is to add colorbar to the graph interactively. That link illustrates how to interactively map different data values into the colormap.
If you want to do that in a programmatic manner, the following link contains an example to changing mapping of data values into the colormap.
I hope this helps,
Ghada
