% symbol not showing in Piechart

[Deepak-kumar-varshney]

Hello dear,

I cloned your demo of Swift ios and checking PieChart it is working fine as expected but it is not showing % symbol in your github demo, can you please look into this?

I am attaching the video for same.

charts.library.demo.video.mov

code

func setDataCount(_ count: Int, range: UInt32) {
    let entries = (0..<count).map { (i) -> PieChartDataEntry in
        // IMPORTANT: In a PieChart, no values (Entry) should have the same xIndex (even if from different DataSets), since no values can be drawn above each other.
        return PieChartDataEntry(value: Double(arc4random_uniform(range) + range / 5),
                                 label: parties[i % parties.count],
                                 icon: #imageLiteral(resourceName: "icon"))
    }
    
    let set = PieChartDataSet(entries: entries, label: "Election Results")
    set.drawIconsEnabled = false
    set.sliceSpace = 2
    
    
    set.colors = ChartColorTemplates.vordiplom()
        + ChartColorTemplates.joyful()
        + ChartColorTemplates.colorful()
        + ChartColorTemplates.liberty()
        + ChartColorTemplates.pastel()
        + [UIColor(red: 51/255, green: 181/255, blue: 229/255, alpha: 1)]
    
    let data = PieChartData(dataSet: set)
    
    let pFormatter = NumberFormatter()
    pFormatter.numberStyle = .percent
    pFormatter.maximumFractionDigits = 1
    pFormatter.multiplier = 1
    pFormatter.percentSymbol = " %"
    data.setValueFormatter(DefaultValueFormatter(formatter: pFormatter))
    
    data.setValueFont(.systemFont(ofSize: 11, weight: .light))
    data.setValueTextColor(.black)
    chartView.usePercentValuesEnabled = true
    chartView.data = data
    chartView.highlightValues(nil)
}

Thanks and regards

Hello,
Regarding the issue of% not displaying in the pie chart, have you resolved this problem?

[Deepak-kumar-varshney]

Hello,
I am not tired as I have a project delivery, so I just added a disclaimer stating, 'Values are in %.'

Thanks and Regards

chartView.data = data
data.setValueFormatter(DefaultValueFormatter(formatter: pFormatter))
Putting setValueModeler later can solve the problem

Sure, I will give it a try when I have time.
