[ROOT] Root: TCanvas range

Hello ,,,

I am getting the following error, which leads to the empty histograms. ANy guess whats going on wrong with my code.

Re: [ROOT] Root: TCanvas range

Hi,

you have a problem with the x-axis range of whatever you try to draw,
e.g. a histogram: it "ranges" from 0.08 to 0.08. We can't help you any
further without a version of your code that we can run and that
reproduces this behavior.

Cheers, Axel.

Re: [ROOT] Python module for easy class generation

Hi,

the advantage now is that users immediately see what to remove when they
want to clean up all files, e.g. when something in their class changed
and ROOT didn't detect the dependencies correctly. And I'm not sure what
happens when writing to ~/ on batch / grid nodes. PWD is usually a safe bet.

Cheers, Axel.

you probably want to have a ROOT-version dependent directory.
also, in well behaved systems (ie: POSIX conformant) putting temporary
files under $TMPDIR (or with tempfile.tempdir in python) should do the
trick of not cluttering $PWD. batch systems not honouring $TMPDIR should
be fixed.

[ROOT] True Random Number Generator (TRNG) Versus (Pseudo-RNG) in ROOT

Re: [ROOT] 2D TEfficiency

[ROOT] Colors writing a Canvas in a root file

Dear ROOTers, 

I'm a bit desperate finding the solution to my problem, so I write you
this mail.
What I want to do is simple I guess, but I did not succeed.
I would like to keep the colors of the TH1F histos when drawing TH1F in
a TCanvas.
  TFile * m_OutputFile = new TFile("ControlPlots.root","recreate");
  m_OutputFile->cd();

  TH1F* tmpup = (TH1F*)nom->Clone();
  TH1F* tmpdo = (TH1F*)nom->Clone();

...//some operations
...

  TCanvas * ctmp = new TCanvas(cname,cname);
  ctmp->cd();

  tmpup->SetDirectory(0);
  tmpup->SetMaximum(maxH*1.2);
  tmpup->SetMinimum(minH*1.2);
  tmpup->SetLineColor(2);
  tmpup->SetMarkerColor(2);
  tmpup->Draw("HIST");

  tmpdo->SetDirectory(0);
  tmpdo->SetLineColor(4);
  tmpdo->SetMarkerColor(4);
  tmpdo->Draw("HIST SAME");

  leg->AddEntry(tmpdo, "-1#sigma","lep");
  leg->AddEntry(tmpup, "+1#sigma","lep");
  leg->Draw();
  ctmp->Write();

then in the ControlPlots.root, the colors of the two TH1F are black...
But doing 
  ctmp->Print("test.png");

gives the correct colors on the .png.
Any idea how to get the colors of the TH1 in the TCanvas in the TFile?

Thanks,
Clément

[ROOT] index font in the axis title

Dear root users,

    About the index font I want to ask your help:

    I define a graph TGraph *gr,and I set the title of Yaxis like below:

      gr->GetXaxis()->SetTitle(" B_{#ita{y}} (GeV) "); 

     here I want to change only the font of the index y with the other fonts(italion or Roma),not the defaut 62,but 
failed to do this. For any suggestion I would apperiate  very much!        

     Thank you!

     regards,

     Fengrong Zhu
