chartView.legend.enabled = true
chartView.chartDescription?.enabled = false
chartView.maxVisibleCount = 12
chartView.drawBarShadowEnabled = false
chartView.drawValueAboveBarEnabled = false
chartView.delegate = self
chartView.dragEnabled = true
chartView.doubleTapToZoomEnabled = false
chartView.pinchZoomEnabled = true
chartView.noDataTextColor = .black
chartView.highlightFullBarEnabled = true
chartView.drawGridBackgroundEnabled = false
chartView.leftAxis.enabled = false
chartView.leftAxis.drawGridLinesEnabled = false
chartView.rightAxis.enabled = false
chartView.rightAxis.drawGridLinesEnabled = false
chartView.xAxis.enabled = true

chartView.xAxis.drawAxisLineEnabled = false
chartView.xAxis.labelPosition = .bottom
chartView.xAxis.valueFormatter = IndexAxisValueFormatter(values: months)
chartView.xAxis.setLabelCount(months.count, force: false)
chartView.xAxis.granularity = 1
let l = chartView.legend
l.horizontalAlignment = .center
l.verticalAlignment = .bottom
l.orientation = .horizontal
l.drawInside = false
l.xEntrySpace = 5
l.yEntrySpace = 2
l.yOffset = 5
l.xOffset = 20
here i am assigning the value to chart
let yVals = (0..<data.count).map { (i) -> BarChartDataEntry in
let val1 = Double(data[i].ownopportunityOwn.roundToOneDigitCroreValue)
let val2 = Double(data[i].ownopportunityAssistby.roundToOneDigitCroreValue)
return BarChartDataEntry(x: Double(i), yValues: [val1, val2])
}
let set = BarChartDataSet(values: yVals, label: "")
set.drawIconsEnabled = false
set.colors = [AppColors.Graph_LightGreenColor,AppColors.Graph_PurpleColor]
set.roundedCorners = [.topLeft,.topRight]
let data = BarChartData(dataSet: set)
data.setValueFont(.systemFont(ofSize: 7, weight: .bold))
data.setValueFormatter(DefaultValueFormatter(formatter: formatter))
data.setValueTextColor(.white)
chartView.fitBars = true
chartView.data = data
var array = [LegendEntry]()
var legendValueArray = [(title: DashboardConstant.K_OWN_WINS.value, Color: AppColors.Graph_LightGreenColor),(title: DashboardConstant.K_ASSISTED_BY_WIN.value, Color: AppColors.Graph_PurpleColor)]
for object in legendValueArray {
array.append( LegendEntry(label: object.title, form: .square, formSize: 10, formLineWidth: 1, formLineDashPhase: 1, formLineDashLengths: nil, formColor: object.Color))
}
self.chartView.legend.setCustom(entries: array)
self.chartView.fitScreen()
self.chartView.notifyDataSetChanged()
chartView.animate(xAxisDuration: 3, yAxisDuration: 3)
