I have a problem with creating map by m_pcolor. I use MatlabR2013a. I tried to create a map by m_map toolbox using same colorbar is used as the one used at'http://koeppen-geiger.vu-wien.ac.at/'.I created the figure by:
m_proj('lambert','longitude',[-34.748 60.8422],'latitude',[26.5861 71.8699]);
m_coast('patch',[1 .85 .7]);
m_pcolor(lon1,lat1,clim);
set(findobj('tag', 'm_pcolor'), 'edgecolor', 'none');
colormap(map);
>> h=colorbar;
>> labels=['ET '; 'BWh'; 'BWk'];
>> h=colorbar;
set(h,'YTickMode','manual','YTick',[1:length(map)]);
set(h,'YTickLabelMode','manual','YTickLabel',labels);
The colors are defined:
m1= [101 255 255]./255;
m5= [255 207 0]./255;
m6= [255 255 101]./255;
I attached the created figure: Map_K_EQ2.jpg. I do not understan why the BWh class is missing in the map and why the lablels do not follow the colors in the colorbar? When I tried to draw these values with same function without defining the colors every values are plotted in the map. This figure is: map_m_eq2.jpg. When I use pcolor I got the same results. Could someone explain me why they do not use every colors in the map?

This looks like an issue similar to your other question. Your 'Ytick' values are 1:length(map), but I have a feeling they should be explicit values found in your dataset.
