# RE: plot graph

```Try this:
<<DiscreteMath`ComputationalGeometry`
data1={{1,10,100},{2,20,200},{3,30,300},{4,40,400}}
TriangularSurfacePlot[data1]
data2={{0,0,1},{1,0,-1},{1,1,1/2},{0,1,0}}
TriangularSurfacePlot[data2,ViewPoint->{0.014, -0.043, 3.383}]

Hope this helps,

Objet:	[mg11037] plot graph

I have a set of solutions. I partitioned them 3 by 3 :
{{x1,y1,z1},{x2,y2,z2},{x3,y3,z3},{x4,y4,z4},...}. I want to plot a 3D
graph.  I know ListPlot[] can treat {{x1,y1},{x2,y2},...}. But
ListPlot3D[] does not  give the graph I want. What is wrong ? I am
using Mathematica 3.0 .

Give an example, I think
ListPlot3D[{{1,10,100},{2,20,200},{3,30,300},{4,40,400}}] should show a
straight line. But it doesn't.

Thanks for help.
