Hi there,
I have the following code to draw a number of histograms on one pad:
Int_t biny = h2->GetYaxis()->FindBin(y2); //get bin from previous mouse
coord
if (hp) delete hp;
if (hps) delete hps;
if (hpol) delete hpol;
if (hpsl) delete hpsl;
if (hpl) delete hpl;
if (hpa ) delete hpa;
if (show_OCP==1)
hp = h2->ProjectionX("OCP",biny,biny); //create OCP slice
if (show_SCP==1)
hps = h3->ProjectionX("SCP",biny,biny); //create SCP slice
if (show_OLP==1)
hpol = h5->ProjectionX("OLP",biny,biny);//create OLP slice
if (show_SLP==1)
hpsl = h6->ProjectionX("SLP",biny,biny);//create SLP slice
if (show_linear==1)
hpl = h4->ProjectionX("Linear",biny,biny); //create linear slice
hpa = h4->ProjectionX("hpa",biny,biny); //create axis
char title[80];
if (selection2==('o'||'O'))
sprintf(title,"Optical Density at Time=%3.3f ps",y2); //set titles
else
sprintf(title,"Differential Transmission at Time=%3.2f ps",y2);
hpa->SetTitle(title);
hpa->GetXaxis()->SetTitle("Energy (meV)");
if (selection2==('o'||'O'))
hpa->GetYaxis()->SetTitle("Optical Density");
else
hpa->GetYaxis()->SetTitle("Differential Transmission");
hpa->GetXaxis()->SetRange(binmin,binmax);
hpa->GetXaxis()->CenterTitle();
hpa->GetYaxis()->CenterTitle();
hpa->SetLineColor(48);
hpa->Draw("L");
if (show_linear==1)
{
hpl->Draw("same");
}
if (show_OCP==1)
{
hp->SetLineColor(kGreen);
hp->Draw("same");
}
if (show_SCP==1)
{
hps->SetLineColor(kBlue);
hps->Draw("same");
}
if (show_OLP==1)
{
hpol->SetLineColor(kRed);
hpol->Draw("same");
}
if (show_SLP==1)
{
hpsl->SetLineColor(kYellow);
hpsl->Draw("same");
}
pad7->cd();
draw_legend();
if (point) delete point;
This works fine, however I want all the histograms to be drawn with option "L",
so I tried "Lsame" and got the following:
Fatal in <operator delete>: storage area overwritten
aborting
but if I just try "L" only the last histogram is displayed! Any ideas?
Thanks in advance
