# plotOptions.waterfall.point.events.drag

Callback that fires while dragging a point. The mouse event is passed in as parameter. The original data can be accessed from `e.origin`, and the new point values can be accessed from `e.newPoints`. If there is only a single point being updated, it can be accessed from `e.newPoint` for simplicity, and its ID can be accessed from `e.newPointId`. The `this` context is the point being dragged. To stop the default drag action, return false. See drag and drop options.
