How to make the pressure contours colorbar concentration the same for all values

How to make the Cp reference colour the same for this coding with different Cp values? Because when I run this coding for the other half of the tail, the Cp colour at 0.008 is in orange colour. How to make the Cp contour constant?

Answer 1

[Walter Roberson]

use caxis() to set the color settings to absolute values.

Sorry, can you help me to add it in my coding because I'm not sure how to do it.

[Walter Roberson]

caxis([0 0.012])

Answer 2

[Seelan Kumar]

This is the other half. But the colour shade at the Cp colorbar changes. So, I couldnt compare the pressure distribution.

Thank you so much.
