How can I set the colorbar for a specific series of value ?

Just like the color bar in this figure. When I save this figure, the color bar shows (500 1000 1500 2000).

I want the color bar to show like this [300:600:900:1200:1500:1800:2100].

Adjust the Limits and Ticks as follows:

cb = colorbar
cb.Limits = [300 2100];
cb.Ticks=300:300:2100;

And then if I want the colorbar to show (0.0 0.5 1.0 1.5 2.0), how can I do this ?

I only can show the result like (0 0.5 1 1.5 2), not including '0.0 1.0 2.0'

Then, you need to change the TickLabels as follows:

oldLabel = cb.TickLabels;
cb.TickLabels = cellfun(@(x) sprintf('%.1f',str2double(x)),oldLabel,'UniformOutput',false);
