Hi ROOTteam

I want to update a point in TGraph. In version 3.00/06 the range of the axis
are not updated.
This worked fine in version 2.25/03

Following macro shows different results in these versions. I like the result of
version 2.25

Thanks Reiner.


{
   gROOT->Reset();

   TCanvas * canvas = new TCanvas("a", "b", 20, 20, 300, 400);
   Double_t x[3] = {10, 20, 30};
   Double_t y[3] = {5,  10, 8};

   TGraph * graph = new TGraph(3, x, y);
   graph->Draw("AL");

   canvas->Update();

   graph->SetPoint(2, 40, 18);
   canvas->Modified();

}
