Logarithmic color scale in 2d histogram

I am looking for a way to change the colorbar of a 2d histogram plotted with DisplayStyle = 'tile' to a logarithmic scale so that one can better distinguish the frequencies. Unfortunally histogram2 has no property 'ColorScale'. Thanks in advance!

Use ruler.scale to set log axis in colorbar.

contourf(randi(1000,25,25))
cx= colorbar();
cx.Ruler.Scale = 'log';
cx.Ruler.MinorTick = 'on';
