Multiple mesh plot with legend

[Xandri]

Hi

Can somebody please assist me to plot a multiple mesh plot with a correct legend.
So far the following works to plot all the mesh plots in one window on one axis...

   mesh(x,y,z)
   hold
   mesh(i,j,k)

However, I can not manage to add a legend that describes each mesh.  The figure just displays
line 1, line2, etc with the colour of the line.

I would like to rename these "lines".

Regards
Xandri
