You can set these strings in your source file, no need to have a
private copy of mp-grap.mpiv

Autoform := "@.0e" ;

or, if you want different formats for the X and Y axes:

string Autoform_X ; Autoform_X := "@.0e" ; % or whatever you want ...
string Autoform_Y ; Autoform_Y := "@.0e" ; 

A few notes:

Autoform_X and Autoform_Y are used if known, otherwise it falls back
on the string Autoform.

The format string uses "@" rather then "%", as % is normally scanned as
a comment.
