Need help with gsplot

[J. Drews]

Hi:

 I am having trouble getting a nice 3d plot with gsplot.

I have created a function called potential like so:

function w=potential(x,y)
w=1.0./sqrt(x.^2+y.^2);
endfunction,

In Octave I do the following:

octave:1> X=[1.0:0.01:5.0]';Y=[1.0:0.01:5.0]';
octave:2> Z=potential(X,Y);
octave:3> data = [X,Y,Z];
octave:4> gsplot [1:5] [1:5] [] data

 However the resulting 3D plot has a very corse mesh. Is this the proper way 
to use gsplot? Is there a mesh size setting? I see that mesh and meshdom are 
alternate commands for 3D. TIA.
