Hi experts,
I have found the method explanation of GetEntries and Integral:
The former return the number of entries matching the selection.
While the later return the integral of bin contents.
But in fact I don’t know what is the mean of bin contents.
And the outputs of these two method are both different.
Does integral consider the events weights?
print(h.GetEntries(), h.Integral())
output: 120000, 12000
