How to make good mesh picture?

I want to make a picture of 3d data. I always have a lot of white dot on picture. I use this command :

mesh(T(1:800,:),E(1:800,:),G(1:800,:)) view (0,90) colorbar

Do you have any NaNs in the data?

What renderer are you using?

get(gcf,'renderer');

Does it go away if you change the renderer?

set(gcf,'renderer','painters');
set(gcf,'renderer','opengl');

I have no NaN data. The problem was the renderer, I am on a Linux computer, so

set(gcf,'renderer','painters');

make the job, but the interactive plot become very slow. I used

print -painters -dpng -loose finalPlot

to make the picture and the result is very good :

Thank you for your help :)
