```Hi,

since

Plot[Sin[# x], {x, 0, Pi},
PlotLabel ->
"\!\(\*SubscriptBox[\"A\", \"1\"]\)[\!\(\*SuperscriptBox[\"x\", \
\"2\"]\),\[Sum] \!\(\*SubscriptBox[\"x\", \"i\"]\)]=" <>
ToString[#]] & /@ {1, 2, 3}

work perfect, can you explain what
"looks horribly if A is more complicated"
may mean ?

Regards
Jens
