Scaling the colormap

Hi,

I have couple of number data as 512x512 matrix data, each point represents the height value. I plot the data by imagesc with gray colorscale and add a colorbar.

Each data has different maximum values as (18, 35, 50...) hence, MATLAB scale the colorbar automatically to the maximum of each data. But I want to use a universal scale maximum such as 50 which I can use for all individual data set.

Is it possible by using a code instead of clicking to colormap editor?

Thanks for help in advance

You can use caxis() to provide a range of values -- min,max

You can also define your own colormap as a matrix map = and then call colormap(map)

thanks for the answer Wayne King.

I also found another method to perform the same operation

set(gca, 'CLim', [cLow, cHigh]); but this command should be used before colorbar command.
