Editor's Note: This was a File Exchange Pick of the Week
A number of people have asked me whether MATLAB can add text to heatmaps to show the exact values. This is very easy to do, however, making a the text robust to resizing, zooming and other operations is a little trickier.
This example shows how to add text to the heatmap and also includes an M-file that shows how to handle zooming and resizing.
