Details on surf plot

Hi,

I have a 3D plot that I generated with this code:

 a= linspace(0.8,1.2,12);

 surf(a,1:59,abs(Z_data),'FaceColor' , 'interp');

and I would like to display the black lines orthogonal to the X axis, but not for the ones orthogonal to the Y axis. I have seen that I can choose the line style for the whole surface, but can I choose a different line style for the different lines orthogonal to the X or Y axis? That is, I want to show each of the a values in the surface grid but not the 59 lines for the y values.

Further, could I label each of these lines orthogonal to the X axis (example like in the image) if I do this:

Thanks in advance for your help!

As an alternative to waterfall, I just learned that you can change the meshstyle of surfaces

h=surf(peaks)
h.MeshStyle='row';

YES! Finally, thanks so much!

I have played around a bit with labeling the lines. Here is my code so far:

figure;hold on
h=surf(peaks(20))
h.FaceAlpha=0.5
h.MeshStyle='row';
y=h.YData; x=h.XData; z=h.ZData;
ind=10; %specify location along x-axis
for i=1:length(y)
text(x(ind),y(i),z(ind,i),num2str(i));
end

You will have to adjust the code so that the end-result works for your own graph. I have used transparency to avoid issues with the label being behind the surface. Another solution (which may be best in your case) would be to put the labels at the end of the curves.

Thanks again!

How would you put the labels at the end of the curves?

[jonas]

It depends on perspective. In the x-z plane you just plot all labels at x(end) or alternatively at x(end)+dx. In my example with peaks this is not a good idea, as all z are equal and the labels become stacked (see attachment). However, it may work nicely for you. Just play around with the indices.

dx=0;
for i=1:length(y)
ha(i)=text(x(end)+dx,y(i),z(i,end),num2str(i));
end

it's probably a good idea to save the handles as well (see ha above) so that you can access and alter their properties after the loop.

cheers

Done!

 dy=0;
 for i=1:length(a)
  ha(i)=text(x(i),y(end)+dy,z(i,end),num2str(a(i)));
 end

Thank you very much for your time and support!

[jonas]

No problem, happy to help!

It sounds like you may want a waterfall plot.

Now the second part of the question:

can I add labels on the lines orthogonal to the X axis?

Cheers!

[jonas]

Right, forgot about that one. Ill edit my answer later today!

thanks ;)
