\ell labels in TH1F pdf plots

[eballabe]

Dear ROOT experts,

Is there a way to write m_ll with the \ell labels in a TH1F x-axis?
I’m currently using m(#font[12]{ll}), however is not the proper symbol for the leptons.

Cheers,
Eric

root [0] auto h = new TH1F()
(TH1F *) 0x7f8a061144b0
root [1] h->GetXaxis()->SetTitle("\\hbox{Title with }\\ell")
root [2] h->Draw()

Note that will not work in pdf. You will need to use ps.
