Hi Mohsen,
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:
Alternatively, you can also check our
RadGanttView control and see if it will handle your actual scenario:

I hope this helps. Should you have further questions please do not hesitate to write back.
Regards,
Hristo
