Hi Greg,
I agree on the subscript issue. However, it is not easy. Grace's
defaults are:
\s \v{-0.4}\z{0.71}
\S \v{+0.6}\z{0.71}
In a \[y_a y_b\] construct LaTeX's defaults are:
\s \v{-0.15000}\h{0.000000}\z{0.667}
\S \v{+0.41289}\h{0.035880}\z{0.667}
(Note, the super-script is also slightly shifted to the right.)
However, with y_a^b the subscript is even lower:
\s \v{-0.24722}\h{0.000000}\z{0.667}
\S \v{+0.41289}\h{0.035880}\z{0.667}
Also, with LaTeX, the zoom factor varies between 0.667 and 0.75,
depending on the text font size.
Personally I find
\s \v{-0.15}\h{0.00}\z{0.71}
\S \v{+0.41}\h{0.04}\z{0.71}
a good compromise. That is, grace's scaling factor and LaTeX's
translations. What do you think? I would build and upload some packages
with these new numbers. Attached you will find my experiments. Black is
the grace default, red the LaTeX default and blue my proposal.
Greetings,
Ionut
PS The real solution for this is a LaTeX input module for grace, which I
have started a long time ago, but didn't manage to finish yet.
