This example demonstrates how to set up the chart so that it shows a tooltip for a series point when a user taps it, and configure a tooltip for each series on the chart.

Line Series Tooltips

Set the chart hint’s Behavior property to the TooltipHintBehavior class instance.
Set each series’ HintOptions property to the SeriesHintOptions object and use the PointTextPattern property to specify the tooltip text pattern.
You can use the following placeholders to specify text patterns for tooltips:
