• (void)chartTranslated:(ChartViewBase * _Nonnull)chartView dX:(CGFloat)dX dY:(CGFloat)dY How to get the index of the data source corresponding to the central location in the sliding proxy

@MonekyHou Not sure if this will help you, but I used something similar to this to highlight the 'middle' point:

func chartTranslated(_ chartView: ChartViewBase, dX: CGFloat, dY: CGFloat) {
    let x = Double(bounds.width/2)
    let selectionPoint = CGPoint(x: x, y: 0)
    let h = getHighlightByTouchPoint(selectionPoint)

    highlightValue(h, callDelegate: true)
}

func chartValueSelected(_ chartView: ChartViewBase, entry: ChartDataEntry, highlight: Highlight) {
    // Here you have access to the entry at the 'middle' point
}
