When I try to run the following code I get the following error. I don’t understand why as when I follow a similar procedure in the console I’m able to call GetObject without any issues on a TFile data type.
void drawspectrum(char *infile)
{
TFile *spectrum = new TFile(infile);
string names[4] = { "c1;1","c1;2","c1;3","c1;4" };
for (Int_t i = 0; i < 4; i++) {
TCanvas* readThis = 0;
spectrum->GetObject(names[i], readThis);
if (i == 0) {
readThis->Draw();
}
else {
readThis->Draw("same");
}
}
}
