    }

func setChart(dataPoints: [String], values: [Double]) {

        var dataEntries: [ChartDataEntry] = []

    //    let da = ChartDataEntry(


        let dataEntry1 = ChartDataEntry(x: Double(0.0), y: 60.0)
        let dataEntry2 = ChartDataEntry(x: Double(0.0), y: 40.0)

            dataEntries.append(dataEntry1)
            dataEntries.append(dataEntry2)

        print(dataEntries[0].data as Any)
        let pieChartDataSet = PieChartDataSet(entries: dataEntries, label: nil)
        let pieChartData = PieChartData(dataSet: pieChartDataSet)
        pieChart.data = pieChartData

        let colors: [UIColor] = [UIColor(cgColor: UIColor.red.cgColor), UIColor(cgColor: UIColor.green.cgColor)]



        pieChartDataSet.colors = colors
    }
Solution

  • You need to set the text color as clear, it will work fine. Check out following change in your current code

    let pieChartData = PieChartData(dataSet: pieChartDataSet)
pieChartData.setValueTextColor(NSUIColor.clear)
pieChart.data = pieChartData
