錯(cuò)誤提示：Type 'ChartDataSet' does not conform to protocol 'RangeReplaceableCollection'

解決方案

// MARK: RangeReplaceableCollection

extension ChartDataSet: RangeReplaceableCollection中粘貼方法

publicfuncreplaceSubrange(_subrange: Swift.Range,withnewElements: C)whereC :

? ? Collection,ChartDataEntry== C.Element{

?? ? ? }
