How to disable highlight for some specific values

[thang2410199]

Hi, I want to disable highlighting for some values on the chart, as I use custom marker and want to only show it on certain values.

Is there any way to do it ? Should the ChartViewDelegate have func like chartShouldSelectEntry -> Bool?

Thank you very much

ask on stack overflow. For this time, any customizations should be done on your side. We cannot satisfy every requirement. You got the source code.

May be this can help

open class BarHighlighter: ChartHighlighter
{
    open override func getHighlight(x: CGFloat, y: CGFloat) -> Highlight?
    {
        guard
            let barData = (self.chart as? BarChartDataProvider)?.barData,
            let high = super.getHighlight(x: x, y: y)
            else { return nil }
        
        let pos = getValsForTouch(x: x, y: y)

        if let set = barData.getDataSetByIndex(high.dataSetIndex) as? IBarChartDataSet,
            set.isStacked
        {
            return getStackedHighlight(high: high,
                                       set: set,
                                       xValue: Double(pos.x),
                                       yValue: Double(pos.y))
        }
        else
        {
            guard let set = barData.getDataSetByIndex(high.dataSetIndex) as? IBarChartDataSet else {
                return nil
            }
            var isOutOfBound = true
            for entry in set.entriesForXValue(Double(pos.x.rounded(.up))) {
                if entry.y >= Double(pos.y.rounded(.down)) {
                    isOutOfBound = false
                }
            }
            return isOutOfBound ? nil: high
        }
    }
