By default, the AllowMoveValue property is set to exDisallow, which means the user cannot rearrange values or series by drag-and-drop. 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 Order property gets or sets the custom display sequence of values or categories by their zero-based indexes. The Position property specifies the position of the serie.

Requirements:

• The Serie's ShowValue property must include the exPoint flag
• When the pointer hovers over a value point, the cursor changes to a hand, indicating that the value can be clicked and dragged

Behavior:

• Click and drag a value to reposition it to another point in the chart. The movement takes effect once the value is dropped, updating the chart order accordingly.
• AllowMoveValue can also be used to rearrange series by drag-and-drop. When a series is moved, the Serie’s Position property is updated to reflect its new order.

For instance, if AllowMoveValue property is:

• exDisallow, disables moving values or series entirely
• exLeftClick, move values or series using a single left-click
• exLeftClick + 0x100, prevent moving individual values (so only rearranging the series is possible)
• exRightClick + exCTRLKey, the user must hold CTRL while right-clicking to move a value or a serie
• including exDblClick requires a double-click to initiate the move
