I run a script and produce the following figure.
AIS_asia_15plane_raw.jpg
I use colormapeditor to adjust the scale (see colorbar near 0 and 1). When I do the same for another figure that has the same range of values (0 to 1) the colorbar is slightly different (0.7 is yellow in the top figure and greenish in the bottom figure):

How do I save the colormap from the first figure and apply it to another?
Thank you in advance for your help!
Best regards,
Alex

After you plot the first figure, use this get call:
cm = get(gca,'Colormap');
Note that the 'Colormap' (link) and the colorbar (link) object are not the same. If you want to save it and use it somewhere else, you can get its handle with:
c = colorbar;
Experiment to get the result you want.

I hope I get points for originality. This works great. Thank you for your time and patience! I suppose that is usually the problem with computers...the user.
Me: "The computer isn't doing what I'm telling it to do."
Answer: "The computer is doing exactly what you are telling it to do! The problem is what you are telling it to do is different than what you think you are telling it to do."

As always, my pleasure!
I learned something from figuring out the problem you were having, and the solution, as well.
Your comment reminds me of a poem posted to the Stanford University computer bulletin board in the late 1970s:
I really hate this damn machine.
I wish that they would sell it.
It won’t do what I want it to,
But only what I tell it!
