Labelling with textext

Labelling with textext

[Troy Henderson]

I'm trying to typeset a numerical label (in math mode) and have space
for a - sign (but not actually typeset the -) after the number in the
case where the number itself is negative.  I am trying this

label.bot(textext("$" & decimal(x) & "\hphantom{-}$"),(x*u,ay*u));

which fails.  If I remove the \hphantom command, i.e.,

label.bot(textext("$" & decimal(x) & "$"),(x*u,ay*u));

the command is successful, but the number being labeled is not exactly
horizontally centered below the point in question since the - symbol
preceding the number pushes it a little to the right.  Thoughts on how
to achieve my desired \hphantom effect?

Thanks,

Can you provide more details? A minimal example works without errors in 
MkII and MkIV.

\starttext
\startMPcode
   x := 1 ; ay := 1 ; u := 1 ;
   label.bot(textext("$" & decimal(x) & "\hphantom{-}$"),(x*u,ay*u));
\stopMPcode
\stoptext
