Hello,
Is there a simple way of plotting histograms of bit masks?
The trigger bits are stored in an integer and I would like to visualise how often the different triggers fired, like in a bar chart.
Many thanks,
Sebastian

Do something like
TH1I *h = new TH1I("h","trigger bit count",32,1,33);
//loop on your data and for each data loop on all bits
for (.....) {
int mydata = ???
UInt_t mask =1;
for (int i=0;i<32;i++) {
if (data & mask) h->AddBinContent(i,1);
mask *= 2;
}
}
