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
```
