Can you be more specific and provide a few lines of code showing what you are doing ?

I want to import the “times signal” like on the picture when plotting figures using TH1D class, i used
\cdot
\bigdot
\bullet
it seems all above do not work
here is the codes:
hist1->GetYaxis()->SetTitle(“B_{E} \bullet E/s^{-1}”);
hist1->GetYaxis()->SetTitle(“B_{E} \cdot E/s^{-1}”);
hist1->GetYaxis()->SetTitle(“B_{E} \bigdot E/s^{-1}”);

[couet]

void dot(){
   auto h = new TH1D("h","h",10,0,10);
   h->GetYaxis()->SetTitle("B_{E} \\cdot E/s^{-1}");
   h->Draw();
}

or:

void dot(){
   auto h = new TH1D("h","h",10,0,10);
   h->GetYaxis()->SetTitle("B_{E} #bullet E/s^{-1}");
   h->Draw();
}

see TLatex documentation and in particular the interface to TMathText.
