Thank you for writing.
The hatch styles used by the standard chart control are not supported out of the box. RadChartView
, however, exposes a powerful API for customizing the looks of the painted elements and you can achieve your task by using a custom renderer: http://docs.telerik.com/devtools/winforms/chartview/customization/custom-rendering
I am sending you attached a sample project demonstrating the suggested approach. I am also attaching a screenshot showing the result on my end.
I hope this helps. Should you have further questions please do not hesitate to write back.
