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.

You're using the older HeatMap from the bioinformatics toolbox.
Instead, use heatmap which supports caxis().
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)
Note other alternatives to heatmap/HeatMap that are supported by older releases of Matlab.
