In general, calculate upper and lower bounds and add them to the
graph. -stcurve- has an -addplot()- option. I don't know what -stplot-
is. If it's a user-written command, you should explain where it comes
from.

Specifically, I am not a survival expert, but I don't think there is
anything such as a 95% c.i. without specifying how it is produced.
