Recommendations on graphing software?

[Adam Bridge]

Happy to give you an example, Gregg.

I'm wanting to plot four sets of data all of which share the same
domain: a constant daily date interval. The ranges of the data sets,
however, are quite different:

1 - calories 0 to 5000 kCal
2 - weight 180 to 200 pounds
3 - exercise minutes: 0 to 500 minutes
4 - carbohydrate consumption 0 to 500 gm

Clearly a single scale that runs 0 to 5000 will reduce weight
fluctuations to what appears to be a straight line - all detail is
lost. So I desire to be able to have the software apply the scaling
and have four different scales, two along the right-hand side of the
graph and two along the left. Or three along the left, whatever is
possible.

Years and years ago I had a nifty program for DEC computers that did
this elegantly and trivially. Excel does not do this nor does Numbers.
It seems to me that there might be some handy-dandy scientfic
visualization package that does this and that's what I'm interested in
finding at a low cost. Free would be nice but certainly less that
$100.

Thank you for your recommendation of KaleidaGraph which I will take a
quick look at!

Best regards,

Adam Bridge
