Charts: Which attribute control the yellow line，like the picture？

how to hide it

DataSet.highlightEnabled = false
highlightEnabled.highlightColor = UIColor.clear

correct answer:

    @objc open func drawHighlightLines(context: CGContext, point: CGPoint, set: ILineScatterCandleRadarChartDataSet)
    {

        // draw vertical highlight lines
        if set.isVerticalHighlightIndicatorEnabled
        {
            context.beginPath()
            context.move(to: CGPoint(x: point.x, y: viewPortHandler.contentTop))
            context.addLine(to: CGPoint(x: point.x, y: viewPortHandler.contentBottom))
            context.strokePath()
        }

        // draw horizontal highlight lines
        if set.isHorizontalHighlightIndicatorEnabled
        {
            context.beginPath()
            context.move(to: CGPoint(x: viewPortHandler.contentLeft, y: point.y))
            context.addLine(to: CGPoint(x: viewPortHandler.contentRight, y: point.y))
            context.strokePath()
        }
    }
