Hello, I have a long-winded question:

I am analyzing data that goes in a sequence. I have:
Segments 1-15 as the first part of my test
Segments 16-18 as the second part of my test.

My macro calculates the time elapsed from segments 1-15 in column AO and
16-18 in column AQ. If the time period is not running, then I have it
specified to pump out "" as the output. What I'd like to do is plot my
y-axis data in column AI in two graphs: AI versus AO and then another AI
versus AQ. I do not know how to make the macro realize when the timer has
started in the segment and when it has ended so that I can plot my graphs, as
the starting row is never the same between files.

Any help would be appreciated!
Thanks!
