How to set the limits of a colorbar for scatter3?

I am trying to make a 3D scatter plot where the colors of the dots are a fourth piece of information in the graph and therefore is independent of the x, y, and z axes. Right now my code is:

scatter3(sub_1_x, sub_1_y, sub_1_z, [], sub_1_c)

But I would like to set the limits of sub_1_c such that it ranges from -1.15e3 to 1.0e3. How can I do this since the colorbar is independent of the x, y, and z axes?

Thank you!

You can use caxis() to set the limits of values used in color computation.

Or you could use pass

min( max( sub_1_c, 1.0e3), 1.15e3 )

instead of sub_1_c

However, now I am wondering if you are asking for the color bar to be reversed, so that the largest value is at the bottom and the smaller value is at the top? If so then you would

cb = colorbar();
cb.YDir = 'reverse';

I would like for the limits to be -1.15e3 to 1.0e3, I'm so sorry for the confusion. I've been trying to figure out how to use caxis, but can't seem to figure out how to incorporate it. I'm also, still not completely sure how to use the pass command that you mentioned?

caxis([-1.15e3, 1.0e3])

or

adjusted_sub1c = max( min( sub_1_c, 1.0e3), -1.15e3 );  %I keep getting the order confused myself!
scatter3(sub_1_x, sub_1_y, sub_1_z, [], adjusted_sub1c);

This worked, thank you so much!
