About the area to click to get the coordinates: imho, it would be better 
to click on the datatip anchor rather than on the label. Indeed, the 
label may be hidden (in 
polyline.datatip_display_mode="mouseclick"|"mouseover"), while the 
anchor is always displayed.
About the tool to do that: to me, there are at least 2 possibilities:

  *   activate the datatip mode + create a contextual menu dedicated
    only to datatips (that was the case in Scilab 5.4.0, before
    refactoring datatips)
  * Out of the datatip mode (which requires a first click to activate
    it), in the general interactive editor : left-clicking on an anchor
    selects the whole curve instead of only the datatip. Then
    right-clicking opens the contextual menu, with actions for the axes
    or the curve:

    It would be interesting to resolve the clicked object: if the click
    position is around an anchor, then in the contextual menu the "copy
    to clipboard" action could be about the only datatip (its coordinates)
    (By the way, in the existing menu, the difference between "Copy" and
    "Copy to clipboard" looks unclear to me).

In practical, i would start

  * either from the datatipmanagermode()
    gateway:/org//.//scilab//.//modules//.//gui//.//datatip//.//DatatipManager//.//start/
  * or from the useeditor()
    one:/org//.//scilab//.//modules//.//gui//.//editor//.//EditorManager//.//start/
