how to customize a colorbar?

Hi,

I try to plot a colorbar next to a plot but to show a color corresponding to the value of the function at that position instead of the range of the colors/values. So I want a layout similar to this:

plot(smooth(rand(1,100), 10));
colorbar('location','southoutside')

But with colors changind according to the value of the function. Any hints?

Thanks

Nevermind...

I wanted something like the following (and I figured out that imagesc can help)

f = smooth(rand(1,100), 10);
figure
subplot(5,1,1:4)
plot(f);
subplot(5,1,5)
imagesc(f')
set(gca, 'xtick', [], 'ytick', [])

Colorbar should not have any bearing on a line plot. Maybe you mean the 'colororder' property of the axes:

>> get(gca, 'colororder')

ans =

         0         0    1.0000
         0    0.5000         0
    1.0000         0         0
         0    0.7500    0.7500
    0.7500         0    0.7500
    0.7500    0.7500         0
    0.2500    0.2500    0.2500

Thanks, but I needed something else. I found how to do it meanwhile (see my other answer bellow).

I like your short video tutorials, by the way :)
