TH1F SetMarkerStyle ineffective

Hi again,
I can’t get the marker style to change in a simple 1d histogram. Whatever I set, the histogram displays with a line.
thanks
Ken

{

gROOT->Reset();

TFile f(“histo.root”,“READ”);

c1 = new TCanvas(“c1”,“sub data”,200,10,700,500);

TH1F *ht_all_ar = new TH1F(“t_all_ar”,“terminations preceeded by AR”,96,-.125,23.875);

ht_all_ar->SetMarkerStyle(30);
ht_all_ar->SetMarkerSize(0.7);
ht_all_ar->Add(callhr_ar);
ht_all_ar->Draw();

c1.Update();

}

If you want to draw with a marker at each bin, use draw option "p"
see the histogram draw options at:
root.cern.ch/root/htmldoc/THistP … nter:Paint
