Hi there,

I'm working on a function that plots a set of data continuously during mouse press. I draw the data with (in short)

tri= DelaunayTri(x, y);
h= trimesh(tri, x, y, z);

I essentially wish to update the z value upon mouse press on given (x, y), by using the set() command. My problem is that I can't seem to understand how the trimesh is built up, even though I've read the documentation. The call

>>get(h)
   ...
   XData = [ (3 by 5972) double array]
   ...

etc., and I don't understand how I should pass my vector (x, y, z)-values into the

set(h, 'XData', ????)

Greatly thankful for guidance and help.

Thank you!

X = get(h, 'XData');

X = [X (new value to plot)];

set(h, 'XData', X);
