Data Points Display

I just realized that the charts I am updating for 2021 differ from the chart of 2018 and before in that the dates for each point of data do not show up at the bottom of the chart. I feel silly that I hadn’t realized that before – I guess I just do it by rote and don’t always pay attention to details. Anyway is it a change in the program or something I have failed to do when I duplicated charts from one year to another? If so, where is the setting because I have gone through and can’t seem to find it.
Thank you.
