Yes, this wouldn't be too hard. Modify:
t_h_tuple = new RealTupleType( time, height);
to:
RealType third = new RealType("third");
t_h_tuple = new RealTupleType( time, height, third);
Modify:
float[][] point_vals = new float[][]{{-3.0f, -1.5f, 0.0f, 1.5f, 3.0f,},
{0.0f, 33.75f, 45.0f, 33.75f, 0.0f,} };
to:
float[][] point_vals = new float[][]{{-3.0f, -1.5f, 0.0f, 1.5f, 3.0f,},
{0.0f, 33.75f, 45.0f, 33.75f, 0.0f,},
{0.0f, 1.0f, 2.0f, 3.0f, 4.0f,} };
Or put into point_vals whatever array of values you want to
display.
If you want to display more or less than 5 points you'll
need to modify:
index_set = new Integer1DSet(index, 5);
Then modify:
display = new DisplayImplJ2D("display1");
to:
display = new DisplayImplJ3D("display1");
and add:
ScalarMap thirdMap = new ScalarMap(third, DisplayZAxis);
display.addMap( thirdMap );
That should do it.
Cheers,
Bill
