If you are using the proportional font in your graph, you
can use tab characters or the sequence \t to line-up
legend elements. Note that the tabs inserted are relative
to the start of the current legend element!
I guess the second part of this is the part that might cause problems.

I don't think that's going to work - assuming tabs work as documented,
that should do a lot better job at dealing with situations where there
are differing number of characters in the strings....
* Max1: 11.56 * Ave1: 5.81
* Max2: 6.43 * Ave2: 4.51
If I'm reading the docs right, using tabs should make this line up fine,
but I think using spaces would mean they'd be off by one.

Sorry - I didn't read quite far enough... "The \g also ignores any space
inside the string if it is at the very end of the string." (I only read
the first part of that). However, the
end is where I wanted to put it. I get the same result from having the
'Combined Ave\: \g',
