How do I position a label below a colorbar?

Is there a way to add a label below a colorbar, as shown in the pic?

I am able to add a label (title) on top of the colorbar, though I am unsure how to position 'Label2' at the bottom of the colorbar so that it uniformly reflects 'Label1', despite having to adjust clims.

plot(1, 1);
c1 = colorbar;
c1.Title.String = 'Label1';
str = 'Label2';
set(get(c1, 'xlabel'), 'string', str, 'rotation', 0);

@dpb how can we label at top of colorbar?

@dpb, how is it possible to make label at top of colorbar and height(colorbar and label ) and data plot height will be matched?

You're almost there...

hCB=colorbar;
hCB.Title.String='Title';
set(hCB.XLabel,{'String','Rotation','Position'},{'XLabel',0,[0.5 -0.01]})

That MathWorks hides all the useful properties is maddening, agreed.

Unfortunately, in colorbar, they also aliased the handles for XLabel, YLabel, and Label to the same object so one is limited to just the two. Anything else one would need to add would have to be an additional text or annotation object.

NB: The above uses an arbitrary position for the y position; another issue is that the title is in figure coordinates in normalized units of figure scaling while the label is in colorbar axis data units.

>> hCB.Title.String='Title'
hCB = 
  ColorBar (XLabel) with properties:

    Location: 'eastoutside'
      Limits: [0 1.00]
    FontSize: 9.00
    Position: [0.82 0.11 0.04 0.82]
       Units: 'normalized'

Thank you very much! It's so much clearer now.
