How it works

This sample

In this sample when onChartDraw event happens chart object model is used to get infomation about event markers from the chart.

When the information is gathered the list is created and onEventMarkerSelect event is listened to show list entries when needed, at the same time scrollTo and selectEventMarker methods are used to show and highlight event markers when user interacts with the list.

You can read more about event markers in Event Markers section and about object model in Updating Chart using Object Model article.
