The MoveValue event occurs when the user performs a drag-and-drop operation to move a category, series, or data value. The AllowMoveValue property specifies the key combination that enables users to move or rearrange values within a series, as well as reorder entire series in the chart using drag-and-drop. The MouseMove event occurs after the drag operation ends and when any of the following properties change::

1. The Order property gets or sets the custom display sequence of values or categories by their zero-based indexes (default, while exDisableMoveCategory (0x100) flag is not included)
2. The Position property specifies the position of the serie (exEnableMoveSerie (0x200))
3. The Data property defines the values of the serie (exEnableMoveData (0x400))
