Thanks Jon, I'm working on your exapmles.
Now that I see your reply, I have to ask another question: I am plotting the
average of the data points over my raw data (to show a smoothed 'trend'
curve), so will I be able to show this when the data series is hidden?
I'd like to hide the raw data and show the smoothed, to summarize.
Thanks, Jim.

You could hide the row/column that contains data for that series. Record a
macro while doing it manually to get the code.

You could also try one of these techniques:
