How to customize Colorbar in heatmap?

32 views (last 30 days)
I want to change the colorbar ticks and labels.
But in updated heatmap function, the colorbar is not output object of heatmap function.
How can I change the colorbar ticks and label?
In attached figure, I want to change colorbar that has ticks only 0 and 1 and each label will be "No" and "Yes", respectively.
mon_label = ["Jan" "Feb" "Mar" "Apr" "May" "Jun" "Jul" "Aug" "Sep" "Oct" "Nov" "Dec"];
figure(555)
h = heatmap(scedata,'CellLabelColor','none');
Ax = gca;
Ax.XDisplayLabels = mon_label;

Try something like this. Using struct can reveal hidden properties like "Colorbar".
cdata = [1, 0, 0; 0, 1, 0; 0, 0, 1];
h = heatmap(cdata);
colormap([h.Colormap(1,:); h.Colormap(end,:)]);
hs = struct(h);
Warning: Calling STRUCT on an object prevents the object from hiding its implementation details and should thus be avoided. Use DISP or DISPLAY to see the visible public details of an object. See 'help struct' for more information.
hs.Colorbar.Ticks = [0.25, 0.75];
hs.Colorbar.TickLabels = {'False', 'True'};
