I can't use RadHorizontalBulletGraph control even if I add reference Telerik.Windows.Controls.DataVisualization.
There is an error ''QualitativeRanges' property does not support the value of the 'QualitativeRange' format.'
I can't use that control even if drag and drop.
If i delete 'QualitativeRanges' property, I can't see that control.
So, what should i do?
