Histogram bars double-wide


I’m generating a few histograms and all but one work fine. This one, however, for some reason has double-wide bars. The data points are (3,1) and (5,1), so they both drag the bar to the left. None of the others do this, and I’m just using the same code. This one only has two datapoints whereas the others have more, but I can’t figure out why each bar would take up two spots. The data is stored in the same way for this chart as in the others. Thanks!
