Problem with bar chart and when the sample ends

[Tsukono]

Hello, I've been having a problem with the bar chart.

The sample is not ending exactly how I want it. I've provided an image of a chart I made in January, and I've set the sample size to 31 days, and the sample to end at 1/2 (1st of February) the bar chart does seem to end at 1/2, however, it seems to just add all the data points after 1/2 into one big column

Ah yeah, just tried this my self. I think you're right there seems to be a bug there, thanks for reporting.
