The Large pointer is the used to open and select menus, menu options, toolbar buttons, modify, and move objects in your charting application. It is also used to display DataTips and the Data Window. You can also use the Large pointer to drag a data stream to the left or right or into another subgraph. The Large pointer provides the same functionality as the Small pointer. The only difference between these pointers is their display size. The Large pointer is only available in your charting application.
To have a vertical line remain on your chart at the last pointer location on charts, enable one of the Drawing >Pointer Tracking Menu bar sequence settings. For more information, see Pointer Tracking Settings.
