Hi Rooters,

I'm working with ROOT 3.05/02 and I have a little probleme with
PolyMarkers as the following macro test.C can show it. If I execute
test.C and I do a zoom with the mouse on the Y axis or if I suppress the
comment before distrib2->SetMinimum(0.7) I have a line of polymarker
which appears on the x axis. Is anybody knows a solution ?

Regards 

Bruno

void test()
{
  TH1F *distrib2 = new TH1F("distrib2","RMS mean vs temperature
(channels > 16)",350,15.,50.);
     //  moyenne sur les differentes mesures à une t°
    distrib2->SetBinContent(50,0.9477); // 20 °C
    distrib2->SetBinContent(150,0.956); // 30 °C
    distrib2->SetBinContent(250,0.9591); // 40 °C
    distrib2->SetBinContent(300,0.9659); // 45 °C

    distrib2->Fit("pol1","","",19.,46.);      
distrib2->SetXTitle("#circ C");     distrib2->SetYTitle("ADC channel");
// 

    gStyle->SetOptFit(11111);
    gStyle->SetStatY(0.5);

    distrib2->SetMarkerStyle(29);  distrib2->SetMarkerColor(4);
distrib2->SetMarkerSize(1.5);  new TCanvas("a2"); 
a2->SetFillColor(10);  distrib2->Draw("p");

}
