STS Graph

[Davia Downey]

Hello Statalisters,

I am creating a graph looking at the survival rates of Face Mask policies in the US and my K-M graph's x-axis goes all the way back to 1960 even though the policies were only in effect in 2020-21 (from the data I have collected). Is there anyway to force the x-axis to a range of dates? I've attached a sample of the data and the code below as well as the graph. Apologies for the large graphic.
