I am making a subplot that has 4 heatmaps. I want to remove individual color bar and add one to the right end of the subplot.

I also want to remove the axes label for each individual heatmap and add one to the bottom as x label and one to the left as y label.

Any idea?

Presuming R2019b or later, use tiledlayout instead of subplot. If not, R2018b introduced sgtitle. Prior to that there are File Exchange submittals for the purpose.

That works for the titles.

For colormap the only easy way will likely be the tiledlayout route -- you should probably be able to associate a colormap with the overall container and turn off for the individual heatmaps. Haven't tried tiledlayout myself yet.

The "actual cell labels" are the labels on the individual heatmap cells associated with the heatmap object, not the axes labels. That's 'XDisplayData' and XDisplayDataLabels'

Ewww... just realized a problem--hHM is a child of the figure, not of an axes object in the figure. Use 'X/YLabel' in the HM object.

>> hHM.XLabel=''; % clear HM object x label

ERRATUM:

My bad, I had other figures around and didn't realize the heatmap object is child of the figure, not of an axes on the figure as most other plot objects have historically been.

Your h2 variable is the handle to the heatmap object you created--it's already an object; use it as is, don't muck on it and make a struct out of it.

hHM=heatmap(...);
hHM.XLabel=[]; hHM.YLable=[];

If you instead mean the actual cell labels, those apparently cannot be removed--altho don't know why one would want to:

>> ylbls=hHM.YDisplayData;  % retrieve labels array for convenience to have some...
>> ylbls(3)={''};           % clear one of 'em...
>> hHM.YDisplayData=ylbls;  % try to write -- fails (not too surprisingly I'd think)
Error using matlab.graphics.chart.HeatmapChart/set.YDisplayData
Empty strings and strings containing only space are invalid y values.
