Hi,

and

Show[ContourPlot[
   ArcTan[f1, f2], {f1, -10, 30}, {f2, -10, 30},(*ContourStyle->None,*)
   ContourLabels -> Automatic, PlotPoints -> 100, Contours -> 5,
   PlotRange -> {-1, 1}, Frame -> True, FrameStyle -> Directive[Thick],
    LabelStyle -> {18, FontFamily -> "Arial"}],
  Graphics[{Red, PointSize[Large],
    Point[{{5, 5}, {9, 9}, {10, 10}, {20, 20}}]} (*doesn't work*)]]

??

Regards
   Jens
