I hope someonw can help me.
I am trying to plot points in 3D space of varying sizes. (These are specific points and sizes that I provide).
I have put the data in an n x 4 matix (we'll call it 'sample' here) of the form:
sample =
{{1, 1, 1, 1},
{1, 2, 3, 3},
{3, 4, 5, 2},
{1, 2, 5, 3},
. . . . (and so on for thousands of lines)
I would like to extract the first 3 terms of each line as the x,y,z coordinates of the points and last term of each line as the size (using the AbsolutePointSize command).
What I came up with is the following command''
Show [ Graphics3D [{ AbsolutePointSize [ Part [ sample, 4]], Point [ Part [ sample, { 1, 2, 3 }]]}]]
I know something is wrong with the Part statements cuz it's extract the whole line, instead of the parts of each line. Also, I don't know that if I do get the Part commands right if it'll work. Should I be using the ScatterPlot3D command instead?
(Sorry if this sounds silly or easy, but this is the FIRST time I have ever used Mathematica)
Thanks,
