[Sea-mat] multiple colormap/colorbars?

[Carlos Moffat]

Hi Lynn,

I'm afraid I only have a partial solution for you, but it might take you 
in the right direction:

Say you have a contour plot/subplot and you've done

1a) H=colorbar (you'll have to have a different handle for each subplot)

Then you do

1b) h=get(H,'children')

or alternatively (in matlab 7)

2) h=findobj('tag','TMW_colorbar') this would give you the same result as 1.

3) once you have access to h, you can change the limits of your colorbar 
by playing with the 'cdata' property. If you used the default length 
colormap, that would be 64x1 (make sure to use a nx1 vector, not 1xn) 
series of numbers. If you change that to, say:

set(h,'Cdata',1:34)

you've done what you want.

Although! it is only a partial solution in that you still have to figure 
out how to translate your real units to "cdata" units, but should be too 
much of a problem.

Cheers,
Carlos
