doublelined x-axis description

I need help. My descriptions for my x-axsis data are very long. Parallel to the axis is difficult because the font size is to small. 45° is to long.
It is possible to doubleline the descriptions?
Thank you and best wishes, Hannah

If you include \n in the text a new line should be created.

Thanks for your fast answer but I take the data from excel and there it is not possible to add this
