Standard tooltips are implemented by the Chart control using two properties:
-
ToolTip: allows for both design-time and run-time tooltips for
DataPoint, Series and LegendItem objects. Special
formatting can be used for these tooltips.
-
LegendToolTip: used to set or get the tooltips of
default legend items created for DataPoint or Series objects, depending on the
chart type displayed. Special formatting can also be used for these tooltips.
Custom tooltips are implemented via the GetToolTipText event, which can be
used to display a tooltip for a chart element that doesn't have a tooltip
property and also to override the tooltip for a chart element that does
have a tooltip property.
