Thank you for your previous response however I would like to know how to recover the Date value from the AxisInfo parameter of the updateInternal method of the AxisToolTip class when used with a DateAxis.
To give context to the question. I am using a DateAxis for the xAxis on this chart and specifying a customised AxisInfoProvider as in the ‘CustomizationRolloverModifierTooltips’ example. When the RolloverModifier highlights some points and if ShowAxisLabels is true then the customised version of the updateInternal method of a customised AxisToolTip is called to to display the xAxis value on the axis.
The AxisInfo object contains a dataValue member variable the question then is: how to convert this back to a Date object.
