Surf with one specific gridline?

Hi,

Is there a simple way of addding in a gridline to a surface plot yet at only one specific point, such as say x = 0?

Say is I have a simple surface plot such as

      figure;
      surf(res_z,res_r,res_ion, 'edgecolor','none');
      xlim([-0.02 0.3]);
      ylim([r_min r_max]);
      view([0.5 90]);
      colormap jet;
      title('zz');
      colorbar;
Is there an easy way to add in such a line? Ideally at a location I can control easily at a later sate (say to a different x value); ideally I dont want to be messing about with annotation lines and the such.

Many thanks.

Is this what you mean?

aH = axes;
plot3(rand(10,1)*0.32-0.02,rand(10,1)*.32-0.02,rand(10,1)*.32-0.02);
hold on
xlim([-0.02 0.3]);
xL = aH.XLim;
yL = aH.YLim;
zL = aH.ZLim;
plot3([0 0],yL,[zL(1), zL(1)],'k--')
box on
aH.XLim = xL; 
aH.YLim = yL;
aH.ZLim = zL;

Hey,

Something like that, yes! However it appears behind the surface plot, not ontop. (It can be seen if it rotate the view yet not on the view I need to set it to).

Thanks

In that case, you might want to try:

 plot3([0 0],yL,[zL(2), zL(2)],'k--')

to place the grid on top.

Please accept the answer that best solves your problem.

That works perfectly, thanks very much!

My pleasure.
