Thank you for writing back.
Currently, RadChartView does support such cursors out of the box. I have added this as a feature request to our Public Issue Tracker under ID 12585. To vote for it and subscribe for its status updates follow this link: http://www.telerik.com/support/pits.aspx#/public/winforms/12585
. We will do our best to implement the functionality in a future release. More votes the item receives, the higher priority it gets in our TODO list.
Thank you for your request. You Telerik points have been updated.
All the best,
the Telerik team
