Hey,
I have what may be a very simple question but I have just
started using Mathematica and can not figure it out. I have
a text file with lines of x y z values seperated by tabs, ie
223.3 233.5 2894.0
How do I get a 3d graph of the points? I would appreciate any help
or a location in the Stephen Wolfram book that explains this. I have tried
various functions ListPlot3D, Graphics3D but they either don't
work or give me a surface that I know does not match the data. I
can read the data from the file correctly. At least I think I have it
in a proper format. I use
pointlist=ReadList["weights.txt",{Number,Number,Number}];
Which give me a list that looks like this
{{-20., -20., 68272.796875}, {-19., -20., 67817.},
{-18., -20., 67363.203125}, {-17., -20., 66911.398438},
{-16., -20., 66461.601563}, {-15., -20., 66013.796875},
thanks,
