I have been using different symbols in the graphical. But when I wanted to write h/2pi (Plank’s constant divided by 2pi) It was not possible. And :frowning: I do not know if there is a way to write this constant into the graphical. thanks :slight_smile:

Try:

{
   gROOT->Reset();
   TCanvas *c1 = new TCanvas("c1","test",600,700);
   // write formulas
   TLatex l;
   TText  t;
   l.DrawLatex(0.1,0.9,"#frac{h}{2#pi}");
}

Thanks, but I wanted to write \hbar like in latex2e. I think it is not possible with ROOT :frowning:
or somebody has other idea? :unamused:
