Thread: how do I plot a constant value in a line graph?

I would like to plot an upper and lower limit in my line graph of
experimental data - is there any easy way to do this? I know I have seen
people do it before with something like ={100,100} or something - but I can't
get it to fill every space across my data range. I am using Excel 2002.

Hi,
IMHO, I would add a line filled with the constant value ...

Cheers
