Tag: DataSeriesIndex

Hello.

When the “RotationAngle” is set for “PolarXAxis” in the range -180 to 0 degrees, the “HitTest” method returns a “HitTestInfo” instance with an invalid “DataSeriesIndex” value. In most cases, “DataSeriesIndex” differs by 1 from the position of the item in the “DataSeries” collection under the mouse cursor.

Please help me to solve this problem.

The attached project reproduces only this problem.
