Remarks

This class is exposed as the e parameter in the GetToolTipText event, and provides the mouse position, tooltip text, if any, and details about the chart element over which the mouse cursor is held when the event is raised.

The GetToolTipText event is raised several seconds after the mouse cursor is held over a relevant chart element.

The ToolTipEventArgs class contains the following properties:

The X and Y properties, which are used to get the mouse coordinates.
The Text property, which is used to get the tooltip for the chart element that the event is raised for. Note that many of the chart elements have a ToolTip, LegendToolTip, and/or LabelToolTip property that you can use to assign a tooltip. These elements include legends, annotations, data points, series, axes, titles, custom labels, and strip lines. This property can also be used to override the tooltip for a chart element, or to set a tooltip for a chart element that doesn't have a ToolTip property.
The HitTestResult property, which provides information on the chart element for which the event was raised.
