Invoked before each ring rendering
func willDisplayRing(_ graphView: CHRadarGraphView, index: Int)

Invoked before each sector rendering
func willDisplaySector(_ graphView: CHRadarGraphView, sector: CHSectorCell, index: Int)
Invoked after each sector rendering
func didDisplaySector(_ graphView: CHRadarGraphView, sector: CHSectorCell, index: Int)
###DataSource methods:
Position and size of graph are automatically determined by center point and radius
func centerOfGraph(_ graphView: CHRadarGraphView) -> CGPoint
func radiusOfGraph(_ graphView: CHRadarGraphView) -> CGFloat
Height for largest sector cell. This would be the largest Y-value on on a classic bar chart.
func largestHeightForSectorCell(_ graphView: CHRadarGraphView) -> CGFloat
The total number of data points that CAN be shown on the graph.
func numberOfSectors(_ graphView: CHRadarGraphView) -> Int
The total number of data points that WILL be shown on the graph. For a graph that shows data around the entire 360 degress, this number should be equal to: func numberOfSectors(_ graphView: CHRadarGraphView) -> Int
func numberOfDataSectors(_ graphView: CHRadarGraphView) -> Int
The number of Y points on the graph. For example, if your largest Y-point is 10, there should be at least 10 rings shown.
func numberOfRings(_ graphView: CHRadarGraphView) -> Int
The angle on the graph where the first data point is rendered. Defaults to 0.
func startingAngleInDegrees(_ graphView: CHRadarGraphView) -> CGFloat
Similar to tableView#cellForRowAtIndexPath, the callback to render data on graph at specific positions.
Stroke colors and line widths:
func sectorCellForPositionAtIndex(_ graph: CHRadarGraphView, index: Int) -> CHSectorCell?
func backgroundColorOfGraph(_ graphView: CHRadarGraphView) -> UIColor
func strokeColorOfRings(_ graphView: CHRadarGraphView) -> UIColor
func strokeWidthOfRings(_ graphView: CHRadarGraphView) -> CGFloat
func strokeColorOfSectorLines(_ graphView: CHRadarGraphView) -> UIColor
func strokeWidthOfSectorLines(_ graphView: CHRadarGraphView) -> CGFloat
