Eliminate vertices from surface plot

Hello,

I have this 3D surface plot and I would like to eliminiate the lines that move in the increasing values of AA so that the other lines can be seen more clearly. These are the set of lines parrallel to the light blue ink edit.

How could I do this?

Thank you.

Hi, could you share relevant code if possible? Thanks.

Yes, sure

surf(X,Y,Z1,'FaceColor','none','EdgeColor','r')
hold on
surf(X,Y,Z2,'FaceColor','none','EdgeColor','b')
surf(X,Y,Z3,'FaceColor','none','EdgeColor','black')
xlabel('AA')
set(gca,'YScale','log')
set(gca,'ZScale','log')

Where each X and Y are vectors and Z1,Z2,Z3 are matrices

Which lines do you want to eliminate? Can you highlight it in the image?

I hope this helps, I understand it maybe wasn't made very clear.

I understand that you want to remove the lines which indicate the increasing values of AA.

You can use the ‘diff’ function in MATLAB, whose documentation link is attached below.

https://www.mathworks.com/help/ident/ref/iddata.diff.html?searchHighlight=diff%20&s_tid=srchtitle_support_results_3_diff%2520

For example if you want to remove the increasing values of y1:

y1_increasing = diff(y1) > 0;  % Identify where the line is increasing 
y1(y1_increasing) = NaN;  % Set the increasing values to NaN

Great thank you very much!!!
