MATLAB: How to put a name / unit in ColorBar

Question

I created an image through some variables obtained.

I wanted to put a ColorBar with the name of the variable and also the unit.

I have accomplished the easiest task, to put a colorbar in the graph.

Can someone help me with how to put the name/units of the colorbar?

This part of the code looks like this:

image(rho); colorbar('location','SouthOutside'); colormap(hsv(10));

Sorry if this question is too simple. I'm just a beginner student in MatLab and programming.

Answer 1

cbh = colorbar('location', 'SouthOutside');
set(cbh, 'Units', 'normal');
text(0, 9/10, 'hello', 'Parent', cbh)
