For dates, there is this workaround: Dates are persisted as integer numbers, December 30th, 1899 being day #0 (allowing negative numbers), so that 2025-01-01 is day #45658 (Gregorian calendar, by which year 1900 was NOT as leap year).

Now, do this:

1. Format your source data as integers. This will allow you to set horizontal axis boundaries.
2. Set your horizontal axis boundaries as you need. Now the diagram axis displays the integer values.
3. In the diagram, format the display of the axis values to the date format you wish.
