# Heat maps in MATLAB

Here at The MathWorks we are always concerned with useful ways of displaying data. A heat map is a graphical representation of data where the values taken by a variable in a two-dimensional map are represented as colors. This is something that is natural for an image, and indeed we have had that in IMTOOL for quite sometime now.

This week’s pick shows how to make a heat map in MATLAB for your own data. This heat map will scale nicely so that the text is always the right size.
