Hi, i need something similar. I used HeatMap function ad i obtained the two charts in attachment. The max values for the two charts are 1 an 0.857. On the two charts the maxi values (1 and 0.857) have the same color green. I need to rescale the second chart to the maximum value 1 in order to obtain the same colours for the same values in the two charts.

caxis does work with HeatMap (and heatmap).
I just noticed that you're using matlab 2015 after writing my answer. I filled in your version info in the Produce/Release panels to the right; are you using r2015a or b?. In the future, remember that it's very important to provide your matlab release info for clear communication and to save time.

If you have a good reason to continue using HeatMap instead, follow this demo to gain access to the axis handle and apply caxis.
HeatMap(magic(9));
ax = findall(0,'Type','Axes','Tag','HeatMapAxes');
caxis(ax, [20,30])
Add a colorbar,
colorbar(ax)

Glad I could help. Note that if more than 1 HeatMap exists the findall command will list all HeatMap axes.
