Hi,

it has been droped because it is useless try

gr = Plot[Sin[x^2], {x, 0, 2 Pi}];

and

DynamicModule[{pnt = {0, 0}},
  gr /. Graphics[gg_, opts___] :>
    Graphics[Append[gg, Tooltip[Locator[Dynamic@ pnt], Dynamic@ pnt]],
     Prepend[Prepend[{opts}, PlotLabel -> Dynamic[pnt]],
      AxesLabel -> {Dynamic[First[pnt]], Dynamic[Last[pnt]]}]]
  ]

and

DynamicModule[{pts = {{0, 1/2}, {2, 1/2}}}, LocatorPane[Dynamic[pts],
   gr, LocatorAutoCreate -> True]]

Alt-Mouse click will add points ..

Regards
   Jens
