Tooltip and Crosshair Cursor
The Tooltip and Crosshair Cursor allow end-users to interact with the chart and obtain detailed information about data points.
The Chart Control uses the Crosshair Cursor when its diagram type is Cartesian (XY) and the Tooltip for all other 2D diagrams. 3D diagrams do not support Tooltips and the Crosshair Cursor.
The Tooltip and Crosshair Cursor provide similar functionality, but they have the following differences:

All diagram types.
The Crosshair Cursor displays all the points that have the same argument or value.
