Text labeling with contourfm colorbar

Hello All,

I have been trying to label a colorbar with text with a figure resulted from the contourfm, while I do have some success I cannot get the first text value to appear.

with a simple contourf it does show up but when i plot with contourfm then it misses values.

What I am after is for the colorbar to include all legend_Names2, staring with the first one on the far left.

I attach the following working code snippet

Data= magic(2); % mock data
legend_Names2={'Opt1','Opt2','Opt3','Opt4'}; % mock legend strings
% 
R = georasterref('RasterSize', size(Data),'Latlim',[30 31], 'Lonlim', [2 3]);
contourfm(double(Data),R,'edgecolor','none')
colormap(flipud(jet(max(max(Data)))));
cbh=colorbar('southoutside');
cbh.XTick = [floor(min(xlim(cbh))):1:ceil(max(xlim(cbh)))];  % create Colobar ticks incrementaly by 1
cbh.TickLabels=legend_Names2;

Thank you all in advance.

The value of floor(min(xlim(cbh))) evaluates to 1. The min value of the colorbar is 1.25. So the Tick for 1 is outside the colorbar and hence not visible.

Try

cbh.XTick = linspace(min(xlim(cbh)),ceil(max(xlim(cbh))),4);

or something similar.

Hello John,

Thank you very much, it works.

But if i may i have only a small question, just to clear it in my mind.

The matrix i have starts from 1 and that is why i used the floor() function, however you are totally right that the xbh lim is 1.25.

But in any case thank you very much, for the swift response.

Kind regards,

George
