I am trying to plot vertical bars from an 8x2 test table; x axis is time from 10:00 - 11:45:

The x-axis stepping is ridiculous: 09:35, 10:04, 10:33, 11:02, 11:31, 12:00.
If I try to change the scale, all x-axis values turn to 12:00 and the bars disappear.

Looks like it might be less tedious to learn drawing bar diagrams with my left foot…
