Try this:

{

   TH1F *h1 = new TH1F("h1","h1",100,-10,10);    h1->FillRandom("gaus",1000);
   h1->SetMarkerStyle(20);

   TLegend *leg = new TLegend(0.1,0.5,0.3,0.7);

   leg->AddEntry(h1,"A gaussian","LEP");
   leg->SetTextFont(62);
   leg->SetTextSize(0.025);

   h1->Draw("histe1");
   leg->Draw();
}
