You could use the widths keyword of xyouts. First write the word outside
of the plot.

You could also have a look in our xyouts_box routine
http://www.fz-juelich.de/icg/icg-i/idl_icglib/idl_source/idl _html/dbase/xyouts_box_dbase.pro.html

This routine did already the job you described.

tek_color
PLOT, findgen(10)
x=RANDOMU(1, 1000)*10 & y=randomu(2, 1000)*10
OPLOT, x,y, psym=1
OPLOT, findgen(10)-0.5 & oplot, findgen(10)-0.6
xyouts_box, 1, 1, 'test 11', /DATA $
, textcolor=2, boxcolor= 3 $
, charsize=3

Please have a look for further routines into
