Drag Points

You can enable draggable-points for one or all series, then users can drag to move a data point in a chart:

DraggablePointComposer.java

    private Charts chart;
...

        //enable drag and drop for a specific series
        chart.getSeries().getDragDrop().setDraggableY(true);
        //enable drag and drop for all series
        chart.getPlotOptions().getSeries().getDragDrop().setDraggableX(true);
