Hello! I need to generate an image from matrix (like fluid jet) and save it as a picture. At the moment I use
mesh(dlmread(my_data.txt))
Then I choose X-Y projection and save it as a picture. It's is very cumbersome but colormap is applied correctly, 'Color data min' and 'Color data max' are set to appropriate min and max values of my data array.
But if I use image(dlmread(my_data.txt)) imwrite - colormap is set to default [0 1] (even though in colormap editor correct min max values displayed). How do I re-scale colormap for range of values in my data? Thank you in advance!

Can you give a short script demonstrating what you have so we can reproduce it?
