MATLAB: How to remove the bars without values in hist3

Question

I'm using the hist3 function to plot a data distribution. I would like to remove all the bars that are zero. Picture 1 (yellow) is the way I want my graph to look but at the moment it looks like picture 2 (blue) where it displays all bars which are zero. Is their an option to change this?

Thanks a lot!

Answer 1

Use histogram2() instead (req. 2015b or later).

% Instead of 
hist3([x,y]);
%use 
histogram2(x,y)

By default bars with 0 height are not drawn.
