Invalid parameter/value pair arguments using Mapping Toolbox

Hello

I´m having problems mapping global temperature using Mapping toolbox. This script is for displaying 3 different figures, annual, winter and summer. When it comes to setting the range and placement of colour bar as:

MinData = 100; % MaxData = 400; % set(gcf,'position',[0.6,0.1,0.4,0.4]); set(gca, 'CLim', MinData, MaxData);

I always get the following error message:

Error using set Invalid parameter/value pair arguments Error in ..... set(gca, 'CLim', MinData, MaxData);

But still the annual image pops out looking fine, without colour bar. Lets say I instead do:

set(gca, 'CLim', [MinData, MaxData]);

No error appears but then all figures turn red, with colour bars.

Any ideas?

Thanks, Hera

Have you called the colorbar command? Instead of using set(gca,..., I recommend giving the color bar a handle of its own, we'll call it cb:

cb = colorbar;
set(cb,'pos',[.6 .1 .4 .4])
caxis([MinData MaxData])

A few examples of tinkering with colorbars and mapped geospatial data can be found here and here.
