I don't think Excel can do that thing with the x-axis labels being in two rows. If the labels are long, you have to put up with overlapping labels or change the angle of them. You might be able to do it by putting in hard line-breaks manually, but that's hard work and definitely means it wasn't done innocently.
Only if it recognises them as dates. If it thinks they're text they get treated as categories.Martin_B wrote: ↑Wed May 20, 2020 9:15 amExcel handles dates better than that, though.

Excel doesn't always handle dates well either.
It could also have been plotting, and then sorting the data.
