plot3 limitation |

Hello All,
I am trying to simultaneously plot an interpolated surface
with the original data points.
In Matlab, one can do this:
mesh(XX,YY,ZZ), hold on
plot3(x,y,z,'o'), hold off
You will see a surface with points showing if the point is
in front of the surface in the view.
If one tried this in octave, and get this message:
"Notice: Cannot remove hidden lines from non grid data"
Here is a line example of the problem so you can easily
see the message. Note that plot3 is from matcompat.
x = [0:0.05:5];
y = cos(2*pi*x);
z = sin(2*pi*x);
gset nohidden3d
plot3(x,y,z,'o')
gset hidden3d
plot3(x,y,z,'o')
I am not sure where the "Notice:" message comes from since grep on
octave sources did not reveal anything, perhaps GNUPLOT?
I have gone into mesh and commented out "gset hidden3d" but this is
not really the preferred solution.
Does anyone know if there is a script that solves this?
The versions in use are shown below.
GNU Octave, version 2.1.36 (i686-pc-linux-gnu) (Note:with a few patches)
with tkoctave 0.3.0
with matcompat-2001.02.25
with G N U P L O T
Linux version 3.7
patchlevel 1
