I've been using the parallel coordinates routine in
visad/examples/parallel and I'm struggling with
coloring the coordinates according to a new
variable. The code looks like:
RealType x = RealType.getRealType("coordinate");
RealType y = RealType.getRealType("value");
SetType xy = new SetType(new RealTupleType(x, y));
FunctionType ptype = new FunctionType(index, xy);
FieldImpl pfield = new FieldImpl(ptype, index_set);
for (int j=0; j<nrows; j++) {
float[][] locs = new float[2][ncoords];
for (int i=0; i<ncoords; i++) {
locs[0][i] = i;
locs[1][i] = samples[i][j];
}
Gridded2DSet set = new Gridded2DSet(xy, locs, ncoords);
pfield.setSample(j, set, false);
}
DataReference parallel_ref = new DataReferenceImpl("parallel");
parallel_ref.setData(pfield);
display.addMap(new ScalarMap(x, Display.XAxis));
display.addMap(new ScalarMap(y, Display.YAxis));
As well as samples[i][j], I have color[j], but I don't know how
to set up the data so that it will know that color[j] is the
color for the jth trace.
