Sometimes when you add a plot to an existing graph, these default settings for the new plot will change the axis to incorrectly show numbers instead of dates.
If the axis is showing numbers and you want to show date or time labels, the axis can be manually changed. To do so, follow these steps:
- Click once on the axis to select it.
- In the Property Manager, click on the Labels tab.
- In the General section, check the box next to the Use date/time format option.
Check the Use date/time format box to use date/time labels.
