If you have a graph where the different series represent different units (e.g. conecentration, pH, and a Ratio), what should you label the Y-axis?

In return, bountiful tits!

Mods, sorry if this meant to be SFW board. Just sandwhich my picture, if you could make it a delicious turkey sub that'd be swell

Personally I'd put them all on a 10 scale and just use that
Label wise I'd be a link to the math of each line so i could work my way back to the orginal value if need be

I'm guessing you dont meant a log scale, just a 1 - 10 type dealie?
Seems like a good idea, i'll give that a playaround in excel.
Also, if I on the X axis I was measuring 4 different pH values, it would seem to make sense to just label them via the tube numbers.
However, apparently that is not acceptable for the report i'm writing.
I can't exactly label the X axis as pH either, as i've already got values for that on the Y axis and the Series.
Any advice would be much appreciated.

in excel you can use atleast two different y-scales.

and im guessing that youre plotting a titration?
in that case id say that the pH has to be in the y because it depends on the volume of added solution

could you just give us a brief run down on what your experiment is?

Of course! I'm sorry, I should've led my post with that.
I'm writing a report for an experiment I did in my Intro To Pharmacology class.
The experiment is, "The Uptake Of Salicyate Into Yeast Cells".
It's to demonstrate the phenomena of the passage of weak acids and bases between lipid membranes.
The report centers on the manipulation of the Henderson-Hasselbalch formulae in order to determine the concentration of salt [A-] within the yeast cell.
I've managed to create a graph of the standard curve with no trouble (R2 of 0.9989, very pleased about that), but the last graph showing the relationship between pH, [Salicylate] and [Salt] (both inside the cell and the supernatant) is proving trickier.
