Hi,
I would like to update the drawing of a histogram periodicially within a loop where it is being filled, i.e.:
TH2F *myHist = new TH2F("myHist", "Titles", 100, -5., 5., 100, 0., 20.);
etaGammaAcc->Draw("LEGO");
for(Int_t i = 0; i < 5000000; ++i)
{
// Values for this iteration
Double_t val1 = someCalculation(); Double_t val2 = somOtherCalculation();
// Fill the histogram
myHist->Fill(val1, val2);
// Plot every 1000 iterations
if(i % 1000 == 0) { myHist->Draw("LEGO"); }
However, this doesn't work - I only get a blank canvas displayed until the loop exits (or I kill the script). Is there a way to do this?
Regards,
James.
