Using TMultiGraph and suppressing existing fits

ROOT
1

Hi, simple question:
I’m using several TGraphs and I’m fitting them - works!
Later I’m using these TGraph for adding them to a TMultiGraph.

When I’m doing Draw() to the TMultiGraph all TGraphs appear with all their fits… is there a simple way to draw the TGraphs without the fit?

I already tried mgr->Draw(“alp0”), but seems the “0” has no influence

Thanks
Georg

Hi Georg,

If you want to disable painting of fit function, you need to set TF1::kNotDraw bit.
For each graph you need to do:

TIter iter(gr->GetListOfFunctions());
while (auto obj = iter()) {
   if (obj->InheritsFrom(TF1::Class()))
      obj->SetBit(TF1::kNotDraw);
}
