Hi
I have a histogram with a number of points so its too many to label on the x-axis.
How do I colour each bar on the histogram a different colour then add a 'colorbar' where I can label the data each coloured bar refers to.
Many thanks

The ability to change the color in each bar of a plot is not built into MATLAB:

You can solve it use my function from FEX:
http://www.mathworks.com/matlabcentral/fileexchange/28513-stembar
Y = 1+rand(10,1);
clrs = repmat(1:10,6,1);
StemBar(1:length(Y),0*Y,Y,clrs(:)')
set(gca,'XDir','reverse')
view([180 0])
colorbar
You can modify source code for 2D case.

In that case I would prefer to label only those bars above a certain value rather than labelling equally spaced out bars that Matlab seems to do when there is not enough space to label all bars.
Can this be done?
e.g label if bar value is > x Thanks
