How to set correct labels is iOS Charts bar chart and colour columns to suit? - ios

Question

I have an iOS Chart, as per the image below, and the labels are showing incorrectly (or not what I want).
As you can see they both say 'Games Played' and are the same colour, as is each bar in my graph.
How can I change the colour of each bar and show the correct respective labels, 'Won', 'Drawn', 'Lost'?
This is my code:
override func viewDidLoad() {
super.viewDidLoad()
let results = ["Won", "Drawn", "Lost"]
let games = [totalWins, totalDraws, totalLosses]
setChart(dataPoints: results, values: games)
}
func setChart(dataPoints: [String], values: [Double]){
let formato:BarChartFormatter = BarChartFormatter()
let xaxis:XAxis = XAxis()
barChartView.noDataText = "you need to provide some data for the chart."
var dataEntries: [BarChartDataEntry] = Array()
for i in 0..<dataPoints.count {
let dataEntry = BarChartDataEntry(x: Double(i), y: values[i])
dataEntries.append(dataEntry)
formato.stringForValue (Double(i), axis: xaxis)
}
xaxis.valueFormatter = formato
barChartView.xAxis.valueFormatter = xaxis.valueFormatter
let chartDataSet = BarChartDataSet(values: dataEntries, label: "Games Played")
let chartData = BarChartData(dataSets: [chartDataSet])
chartData.addDataSet(chartDataSet)
barChartView.data = chartData
barChartView.leftAxis.forceLabelsEnabled = true
barChartView.rightAxis.forceLabelsEnabled = true
barChartView.xAxis.granularityEnabled = true
barChartView.xAxis.granularity = 1.0
barChartView.leftAxis.drawGridLinesEnabled = false
barChartView.rightAxis.drawGridLinesEnabled = false
barChartView.xAxis.drawGridLinesEnabled = false
barChartView.rightAxis.enabled = false
barChartView.drawGridBackgroundEnabled = false
self.barChartView.xAxis.labelPosition = XAxis.LabelPosition.bottom
}

Simply add chartDataSet.colors = ChartColorTemplates.material() or you can add your array of UIColor in order to customise according to your need.
