How to fix color data min/max (constant) in colormap editor?

Dear,

I have 1 frame, containing 400 images.

Link download if you want to try: https://drive.google.com/open?id=1lHMUzYB6xVIRYDu7uiujVqsM8eimg3KS

What I want is, after export this frame into images. The color map will follow my fix color data min and max.

The color will darker and brighter follow that min and max value.

Another question is, I want my color map divide into as many part as possible, (like the below image)

Thank you for your help.

I found this answer for the first question

set(gca, 'CLim', [cmin cmax]);

I am waiting for the second one.

Thank you.

there is no built in color map that looks like that.

it looks to me as if it would be easiest to build it in hsv with blue hue and 0 saturation at the left, increasing to full saturation at the middle then switching to fully saturated red and decrease saturation to the right. Then hsv2rgb. You should be able to create it with arbitrary size .

Thank you for your answer. I will try.

This is my first approximation of the colormap (attached). It isn't exactly what you want, but it is what I have so-far.
