Thread Subject: mesh plot question - "see through" wire frame

1. Is there a command that will make my mesh "see through", so I'm left with only a wire frame?

2. Can I adjust the color of the frame when I get there?

- Thanks!

% Make a mesh
[X,Y] = meshgrid(-3:.125:3);
Z = peaks(X,Y);
M = mesh(X,Y,Z);
axis([-3 3 -3 3 -10 5])

% Now set the faces to "see-through"
set(M,'facealpha',0)

% Make a uniform color
set(M,'edgecolor',[.2 .4 .9])

For more general color manipulations, see the colormap and cdata.

Like this?

[X,Y] = meshgrid(-3:.25:3);
Z = peaks(X,Y);
plot3(X,Y,Z)
hold on
plot3(X',Y',Z')
grid on
axis([-3 3 -3 3 -10 5])

this should give you that "wireframe look" you are looking for.

Cheers,
Florian

I would point out that I have sometimes seen
problems when using transparency. Large plots
with some degree of transparency will occasionally
cause matlab to crash. So I would avoid setting
the faces to be fully transparent for no good
reason. A better solution may be just to set the
faces to have a color of 'none'.

set(M,'facecolor','none')

In addition, it is likely to be faster.

Good point, John. I haven't seen any crashes from doing what I did, but I believe you are probably correct about the speed.
