Vertical labels on line graph widget possible?

[Newbie4]

Is it possible to have vertical labels on the x-axis in the line graph widget?

The labels on that axis are long and overlap to where they are unreadable. I tried making them a smaller font and cutting them off lengthwise but they were difficult to read.

Is there a way to rotate them so the are sideways (vertical) ? If there is not a property or way to do that, would it be hard to edit that widget and add it as a property?

Thank you

TMHO, this is not difficult but will take a lot of time for typing and scripting (doing all the text measurements, resizing the widget if needed).
That's why I prefer to use short labels connected to a legend/footnotes for more text.
