When there are multiple plots in the main window. One can plot the selected points onto a another plot by dragging them to that particular plot panel. If the plot panel on which the points are dragged in has already some plotted points, user is prompted with a context menu asking user whether the dragged points should be added or replaced to the already plotted points.
Similar operation can be done by clicking "Plot selected points in an empty plot" icon or "Plot selected points in an empty plot" menu item in the "View" menu.
