Create Heatmap with custom colorbar (i.e. <0.01, <0.05)

Hi,

I'd like to plot a heatmap from my NxN matrix data. These values range from 0 to 1 and I want to have a color for each values smaller than 0.01, 0.05, 0.1, etc. and a color bar which displays '<0.01', '<0.05', etc.

I saw this in a presentation and I was wondering how to do that.

Thanks for help
