How about this:

PRO PlotNumbers, x, y

IF N_Elements(y) EQ 0 THEN y = RandomU(-3L, 80) * 100
npts = N_Elements(y)
IF N_Elements(x) EQ 0 THEN x = Indgen(npts)
Plot, x, y, BACKGROUND=FSC_Color('ivory'), COLOR=FSC_Color('navy')
OPlot, x, y, COLOR=FSC_Color('ivory'), PSYM=SymCat(15), SYMSIZE=2.0
XYouts, x, y, StrTrim(Sindgen(npts)+1, 2), COLOR=FSC_Color('red'), $
ALIGN=0.5, CHARSIZE=0.75

END

You can find FSC_Color, SymCat, and other programs you need in
the Coyote Library.
