Hello Murray, How about this: f[{x_, y_}] := {2 x + 1, y + 2}; DynamicModule[{pt1 = {1, 1}}, {LocatorPane[Dynamic[pt1], Framed@Graphics[{}, PlotRange -> {{0, 5}, {0, 5}}, Axes -> True]], Framed@Graphics[{}, PlotRange -> {{0, 5}, {0, 5}}, Axes -> True, Epilog -> {PointSize[Medium], Dynamic@Point[f[pt1]]}]}]
