Enable Data Editing

It provides drag and drop support to the rendered points. Now, the location or value of the point based on its y value can be changed. To enable the data editing, set the enable property to true in the drag settings of the series. Also, the color can be set using fill property and set the data editing minimum and maximum range using minY and maxY properties.
