[Nallamsetty]

here is the code, please help me...

fileprivate func setLineChart(_ lineChartView: LineChartView, dataPoints: [String], values: [Double]) {

        // 1 - creating an array of data entries
        var dataEntries: [ChartDataEntry] = []
        for i in 0..<values.count {
            let dataEntry = ChartDataEntry(x: Double(i), y: values[i])
            dataEntries.append(dataEntry)
        }
        
        // 2 - create a data set with our array
        let lineChartDataSet = LineChartDataSet(values: dataEntries, label: "LINE CHART")
        lineChartDataSet.setColor(UIColor.blue)
        // lineChartDataSet.drawCubicEnabled = true
        lineChartDataSet.mode = .cubicBezier
        lineChartDataSet.drawCirclesEnabled = true
        lineChartDataSet.lineWidth = 1.0
        lineChartDataSet.circleRadius = 5.0
        
        
        lineChartDataSet.drawFilledEnabled = true
        lineChartDataSet.fillColor = .green
        
        // lineChartDataSet.fillAlpha = 65 / 225.0
        lineChartDataSet.highlightColor = UIColor.orange
        lineChartDataSet.setCircleColor(UIColor.blue)
        // lineChartDataSet.circleColors = [UIColor.red]
        // lineChartDataSet.label = ""
        lineChartDataSet.drawHorizontalHighlightIndicatorEnabled = true
        
        //3 - create an array to store our LineChartDataSets
        var dataSets = [IChartDataSet]()
        dataSets.append(lineChartDataSet)
        
        //4 - pass our months in for our x-axis label value along with our dataSets
        let lineChartData = LineChartData(dataSets: dataSets)
        lineChartData.setValueTextColor(UIColor.black)
        
        // x-axis
        lineChartView.xAxis.labelPosition = .bottom
        lineChartView.xAxis.drawGridLinesEnabled = true
        lineChartView.xAxis.granularity = 1.0
        lineChartView.xAxis.setLabelCount(dataPoints.count, force: true)
        lineChartView.gridBackgroundColor = UIColor.red
        lineChartView.data = lineChartData
        
    }
