Specified by:

calculateOffsets in class Chart<T extends ChartData<? extends DataSet<? extends Entry>>>

getAngleForPoint

public float getAngleForPoint(float x,
                              float y)

returns the angle relative to the chart center for the given point on the chart in degrees. The angle is always between 0 and 360°, 0° is NORTH, 90° is EAST, ...

Parameters:
