Re: Simple? 3D Plotting Problems

Tracy:

data = Table[Random[Real, {.5, 2.5}], {6}, {5}];

In[31]:=
ListPlot3D[data]

ListPlot3D[data, MeshRange -> {{0.05 , 3.0}, {0.05 , 3.0}},
  PlotRange -> {0, 3}]

You can track down this sort of thing in the HelpBrowser
1) Look up ListPlot3D: find that ListPlot3D has the same options as
SurfaceGraphics
2) Look up SurfaceGraphics: find (editted)
MeshRange   Automatic  the required range of x and y coordinates for the
plot
3) Look up MeshRange: find
MeshRange -> {{xmin,xmax},{ymin,ymax}} specifies ranges in x and y....

The Help Browser really is helpful!
