I am actually talking about the curve name in legends. The curve name
is "yvector vs xvector". Which is necessary in a context free way,
like in a list of curves. But you might want to have the curve still
called "yvector vs xvector" in the curve lists (because you also have
a "yvector vs zvector" in a different plot) but in this particular
legend, you want to call it something different, like "case 1:
g=2200". How should we do that in the UI?
i) a new text entry in the curve dialog "Legend entry name" with a
"[x] Use Name" checkbox.
ii) something else

Upon looking at it, I agree that this is sub-optimal. The rule for 1
curve, no quantity should be Name [Units]. We've never had this case,
no top label.

Yes. There should be a margin setting.

This is a tricky one. One of the plots had huge Y axis numbers, which
pushes everything out. I guess we could try moving the space to the
left of the Y label. Later. Remind me once the other stuff is done
(or put in a wishlist with "try" in the title)

Still thinking about it. You might be right. Once I've re-factored,
it will be trivial to try different things.

What we need is a matrix of cases with desired XLabel, YLabel,
TopLabel, and Legend. Can you make one (maybe a google doc or a
document in DevelDocs. )
By cases, I mean, what is defined, how many relations, what is the
same, what is different, etc. There are lots of cases.
Name is always defined. Quantity and Units are independently optional.
