[racket] PLoT - is there a way to have a non-numeric, categorical x-axis (and possibly display histograms)?

Hi,

I'd like to know if using PLoT, there is any way to have the x-axis values being categories (like e.g., weekdays...), and having the x-axis labeled accordingly?

Ideally, it's histograms I'd like to show, but I assume this is not possible, or is it somehow?

Many thanks for your help,
Sigrid
