How to hide zero values in bar3 plot in MATLAB

Question

I\'ve got a 2-D histogram (the plot is 3D - several histograms graphed side by side) that I\'ve generated with the bar3 plot command. However, all the zero values show up

Answer 1

My problem was not zero values, but NaN values (which are converted into zero values inside of bar3). I wanted to keep displaying elements with values zero, but not the elements with value nan. I adjusted the code slightly, and it worked perfectly:

for i = 1:numel(h)
  index = logical(kron(isnan(z(:,i)),ones(6,1)));
  zData = get(h(i),'ZData');
  zData(index,:) = nan;
  set(h(i),'ZData',zData);
end

Thanks!
