Printing x values from an csv file

[hobbyist]

I am using a .csv file with measurements. On the first column of the .csv file there are timestamps, such as this:
01/24/2021 12:45 PM
(after 100 measurements)
02/25/2021 04:34 PM
. . .
etc.

On the 2nd column there are some numbers. When I plot the data I need to put x values something. Can it put automatically the date time for every lets say 100 measurements, on x axis? Is there any better way? From here: https://matplotlib.org/3.3.3/api/_as_gen....plot.html
I tried:

plot('date', 'visitors', data=obj)

but does not seem to work...on x values it prints me numbers from 0 to 2000, with step 200.
