In this simplified code below, I'd like to display two plots within Manipulate, and use the Locator controltype to set the value of x relative to its position within the first plot only. With the Print[x] command inserted it is obvious that the locator is using the coordinates of the entire graphics plane. 

Manipulate[ Print[x]; GraphicsRow[{ListLinePlot[{x, {0, 0}}, PlotRange -> {{0, 2}, {0, 2}}], ListLinePlot[{x, {2, 2}}, PlotRange -> {{0, 2}, {0, 2}}]}], {{x, {0, 0}, {2, 2}}, ControlType -> Locator}]

Just replace GraphicsRow to Row!

Manipulate[ Row@{ListLinePlot[{x, {0, 0}}, PlotRange -> {{0, 2}, {0, 2}}, ImageSize -> 200], ListLinePlot[{x, {2, 2}}, PlotRange -> {{0, 2}, {0, 2}}, ImageSize -> 200]}, {{x, {0, 0}, {2, 2}}, Locator}]

enter image description here

Also instead of ControlType -> Locator you can use just Locator.

P.S. Does anybody know how to choose the second plot?

  • $\begingroup$ To choose the second plot, The only way I could figure out was to explicitly construct the LocatorPane around the second plot. Otherwise it seems to automatically pick the first Graphics it finds. E.g.: Manipulate[ Row@{Dynamic@ ListLinePlot[{x, {0, 0}}, PlotRange -> {{0, 2}, {0, 2}}, ImageSize -> 200], LocatorPane[Dynamic@x, Dynamic@ListLinePlot[{x, {2, 2}}, PlotRange -> {{0, 2}, {0, 2}}, ImageSize -> 200]]}, {{x, {0, 0}, {2, 2}}, ControlType -> None}] $\endgroup$ Commented Oct 3, 2013 at 20:59

Using LocatorPane we can do this:

DynamicModule[{pt}, GraphicsRow[{ LocatorPane[Dynamic[pt], Dynamic@ListLinePlot[{{0, 0}, pt}, PlotRange -> {{0, 2}, {0, 2}}]], Dynamic@ListLinePlot[{{2, 2}, pt}, PlotRange -> {{0, 2}, {0, 2}}] }]]

locators
