回答： Rohan Kadambi 2023-12-12

How can I label the color bar (e.g. 'Pressure (Pa)' or 'Temperature (K)') for a heat map created with h = heatmap(x,y,data)? I don't see a colorbar handle or property in h.

Hi, how can I move the title to the right side?

Its already on the right. Unless your figure window is too small. Try resizing it.

set(gcf, 'Position', get(0,'Screensize'));

Alternatively, you can manually edit the location after plotting

plotedit(gcf)

You can reveal hidden properties of handle objects by casting them to struct. Doing this to the HeatMapChart handle reveals a handle to the colorbar:

h = heatmap(rand(10));

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.

ylabel(hs.Colorbar, "Colorbar Label");

Also looking for a solution ... no luck so far.

I am looking for the same. I'd appreciate any hint to get around this problem.

I was really happy to see them introduce the heatmap function but it again is quite inconsistent with the rest. I can't get a handle on the colorbar label to set the string like one usually can. Really annoying for the diagram tools to be so inconsistent still, I thought this was gonna go away when they changed it some years ago.
