Thank you for writing.
The chart displayed in the attached screenshot suggests that you might need a Gantt-like series. Currently, this kind of series is not supported. We have a feature request logged on our feedback portal here: https://feedback.telerik.com/Project/154/Feedback/Details/199809-add-radchartview-gantt-like-series
. I have also added a vote for the item on your behalf.
For the time being, if it fits your local setup you can use a normal bar series
and change the orientation of the chart area:
.radChartView1.GetArea<CartesianArea>().Orientation = Orientation.Horizontal;
Alternatively, you can also check our RadGanttView
control and see if it will handle your actual scenario: http://docs.telerik.com/devtools/winforms/ganttview/ganttview
I hope this helps. Should you have further questions please do not hesitate to write back.
