Actually, once I thought about it, it could be very appropriate to overlay each year's monthly data. You would then see the trend for all March's together. That may be o.k.

I don't know how people feel about not being able to compare this year against last year, though. Hmmmm.

If it were possible and would not take a ton of work I think I would like to see each year overlayed on the same graph. I'd gladly go back and add in the year to the data. The ideal would be for each year to be plotted with a different colored line.

Easy for me to say what I'd like, but it could be difficult to program.
