That's not how column bar charts work. Each column represents one X-axis time period or category.

1. How will you display if the machine runs for 30 minutes?
2. What does the height of a bar mean?

Normally you would use a horizontal bar chart for this and "stack" the time periods left to right. There's an example in [Ribbon chart in Ignition Reporting module](https://forum.inductiveautomation.com/t/ribbon-chart-in-ignition-reporting-module/88209).
