How do I control the min and max values for colorbar within an m-file.

331 views (last 30 days)
I am currently writing a program that produces a movie of the position and energy level of numerous electrons in a device. I am currently using the colorbar to display the energy level but can't figure out how to set the min and max levels within the m-file. I know you can do this within the plot of each frame, but this obviously won't work for me. I'm using the plot command "scatter3". Any suggestions would be greatly appreciated.
All the best,
Josh

Try using the caxis command. This command adjusts the CLim property of an axes. You can that property directly if you want more low-level control. But caxis is a quick, convenient way of doing it.
Here's a quick example:
scatter(2:9, 2:9, [], 2:9, 'filled')
colorbar
caxis([1 10])
