How to plot 4 lines that will be different each day of the week.

["jbclem" <jbclem@xxxxxxxxxxxxx>]

This is for TS4.

Each morning I'd like to be able to enter 4 values  and have 4 horizontal
lines plot at those values, that day only, but be retained on that days
chart as the week progresses, and new lines are plotted on subsequent days.
I  can't figure out how to do this with values(or inputs) that come from
outside and aren't part of a formula.  Do I have to have a new formula for
each day of the week, or each day of the month?  Does anyone know how to
write this in Easy Language?
