# How to plot a 3D list of points [closed]

I have 3 variables {Eff[i][j], i/15, j/100}. I need to plot them as a 3D figure, the height of the figure is Eff[i][j], which is a series of numbers, i and j are integers ranging from 1 to 150.

How can i do this in Mathematica?

Thanks

What about ListPointPlot3D? –  PlatoManiac Oct 22 '12 at 18:15

PlatoManiac beat me to it in the comments, but if you assume eff is defined like such:

eff[i_,j_]:=i^2-2*j


Then you can plot using ListPointPlot3D

ListPointPlot3D[Table[{i, j, eff[i, j]}, {i, 150}, {j, 150}]]


And yes, those are all points if you want to zoom in.

Grahics3D was used for plotting a Table:

points = Table[Point[Table[Random[], {3}]], {100}];


and also for labelled 3D plots, this is the full example:

Clear["*"];
data = ({
{0.327923, 0.692999, 0.684839},
{0.742393, 0.809279, 0.066263},
{0.299856, 0.396878, 0.923915},
{0.641218, 0.538044, 0.084668},
{0.624990, 0.009596, 0.555116},
{0.0193513,0.575685, 0.428527},
{0.638989, 0.718369, 0.039039},
{0.983107, 0.078511, -0.250713},
{0.711116, -0.290107, 0.393672},
{-0.508319, 0.901837, 0.223845}
});
labels = Array[0 &, Length[data]];
Do[labels[[i]] =
Graphics3D[
Text[i, {data[[i, 1]], data[[i, 2]], data[[i, 3]]}]], {i, 1,
Length[data]}];
Show[
labels,
Boxed -> False,
Ticks -> Automatic,
Axes -> True,
AxesStyle -> {LightGray, LightGray, LightGray},
AxesOrigin -> {0, 0, 0},
AxesLabel -> {"X", "Y", "Z"},
ImageSize -> 500]

perhaps you could merge your two answers... –  cormullion Oct 23 '12 at 13:36

needs a Point` function? –  cormullion Oct 23 '12 at 9:44
