Thanks Jerry, (and to the others who took time to think about my question) ,
but I think ListSurfacePlot only works only on regular coordinate spacing?
Correct me if I'm wrong.
My Mathematica code looks like this:
In[1]:=
SetDirectory["c:\Documents and Settings\P. Lindsay\DESKTOP\alanr"];
In[2]:=
t=Table[ReadList["cpp_smlX.txt",Number,RecordLists -> True]];
In[3]:=
ScatterPlot3D[t,BoxRatios->{10,10,10},Axes->True,
AxesLabel->{"fair","num","ratio"},ViewPoint->{3.0,2.5,0.3}]
and works but is incredibly slow ( pc 450Mz 190Mb ram, Mathematica 3 ). My Mac Cube
( 300 Mb ram, Mathematica 4 ) wont even look at the problem - just hangs up. Any
thoughts about why?. Tried fiddling with kernel memory allocation. The
competition ( vs 6 ) works easily ( pointplot3D ) on either platform but not
yet for surface plot.
Can I get a surface plot of the data in "cpp_smlX.txt" - remembering that
the data is non-linear spacing ?
Thanks for your thoughts,
Peter Lindsay
