plot_colorbar

Plot a colorbar as a figure for publication.

Description

Plots a vertical or horizontal colorbar for inclusion in a publication. The specified colorbar can be plotted either horizontally or vertically, and a function handle can be passed in to allow the use of different colormaps.

Written during some recent work, and then cleaned up and published here in case it's useful to anyone else.

Examples:
h1 = plot_colorbar([100, 5], 'h', 'Test Colormap')
h2 = plot_colorbar([150, 10], 'v', 'Test Colormap', @hsv)

• MATLAB release: MATLAB 7.4 (R2007a)

thank you to have thought there. This is a very good idea and very useful!

Addition of a way to modify the ticks to a user defined limit would be helpful. Thanks - just what I was needing.

does not work for me: It requires an axis handle
map = colormap(axishandle, cmap(dims(1)));

and since it can not be used as an exact replacement of the orignal colormap I can not use without rewriting most of my and of this plugins code

I was able to get my desired result (scale from [0 8]) by changing one the lines to set(gca, 'yticklabel', [0, ticks/10]); and then running the program with the limit 80.
