surf plot grid line density

Hi everybody,

I am trying to resolve this the last couple of days but no lack. I have a surf plot and I need to have a certain amount of points on it for detail. I need the surf plot to be red. No colormap. The grid because of resolution is making my plot totally black at points. And I can't see the details. Is there a way to make the grid less dense without decreasing the resolution of my data? Alternatively is there a way to use shading on the red surface plot to show the details of it?

here is a link of one plot using a grid and one without. None of them is good enough: Image

Any help is appreciated, thanks

You seem to have learned how to turn off the gridlines. The best thing I can think to do is:

hold on

Then take a subset of your data (like every third column and third row or whatever. Then surf that, with color none for the facecolor. That should overlay a grid with less resolution.

clever! thanks!

Hi,

the suggestion by Doug could look as follows (worked for me):

figure
S = surf(XX,YY,ZZ);
    s.EdgeColor = 'none';
hold on

spacing = 40;  % play around so it fits the size of your data set

for i = 1 : spacing : length(XX(:,1))
    plot3(XX(:,i), YY(:,i), ZZ(:,i),'-k');
    plot3(XX(:,i), YY(:,i), ZZ(:,i),'-k');
end

Best regards,

The second line in the for loop should read:

plot3(XX(i,:), YY(i,:), ZZ(i,:),'-k');

The grid pattern in this solution more closely follows the surface. The solution given by Doug may provide some clipping artifacts if the grid pattern spacing is too large.
