I think in general, you would do something like this, probably
three times:
x = [0.0, 0.5, -0.8, 0.8, -0.5, 0.0]
y = [1.0, -0.8, 0.3, 0.3, -0.8, 1.0]
UserSym, x, y, /Fill
Plot, Findgen(11), PSym=-8, SymSize=2.0
PlotS, [0.2, 0.3], [0.85, 0.85], PSym=-8, SymSize=2.0, /Normal
XYOuts, 0.33, 0.845, 'This is the star line', /Normal
Cheers,
David
