Hi,
I'm wondering if there's a way to plot tuples of (x, y, z) data
points (as markers, surfaces, contours, etc.) which is similar to
TGraph? I couldn't find anything called TGraph2D, so I assume it
doesn't exist. I _don't_ want to use TH2 since the data is not counts
but rather tuples. What I'd like to do is something along the lines
of
TGraph2D* g = new TGraph2D(n);
for (Int_t i = 0; i < n; i++) {
Double_t x = ...
Double_t y = ...
Double_t z = ...
g->SetPoint(i, x, y, z);
}
I know you can do something with TMultiGraph + TLegend (which is nice)
but it does not produce surface plots, and further, if you have tuples
(x,y,z,v), what I'd like was to plot
d = f(x,y, z=z0)
d = f(x,y, z=z1)
d = f(x,y, z=z2)
that is, d as a function of (x,y) at constant z, put them in the same
TMultiGraph and plot it as (superimposed) wire plots.
If I've overlooked something, I beg your pardon. Otherwise, I'd
really like to see this in ROOT.
Yours,
