Correct data not showing in ios Charts - ios

Question

Im using Charts Version 3.0.1. Im currently teaching myself Swift by converting my Rails project. I have no knowledge of Objective C so please bear with me; I've done ok so far.
My code below is/may not be formatted correctly as Im missing the days array in the PieChart:
Numbers seem not to be correct. The code:
#IBOutlet weak var chartView: PieChartView!
override func viewDidLoad() {
super.viewDidLoad()
let days = ["Mo", "Tu", "Wed", "Thur", "Fri", "Sat", "Sun"]
let gross = [11.00, 90.95, 250.00, 40.90, 60.88, 99.99, 25.00]
setChart(dataPoints: days, values: gross)
}
func setChart(dataPoints: [String], values: [Double]) {
var dataEntries: [ChartDataEntry] = []
for i in 0..<dataPoints.count {
let dataEntry = ChartDataEntry(x: values[i], y: Double(i))
dataEntries.append(dataEntry)
}
let pieChartDataSet = PieChartDataSet(values: dataEntries, label: "Gross Income")
pieChartDataSet.sliceSpace = 2.0
let pieChartData = PieChartData(dataSets: [pieChartDataSet]) // somewhere here confuses me.
var colors: [UIColor] = []
for _ in 0..<dataPoints.count {
let red = Double(arc4random_uniform(256))
let green = Double(arc4random_uniform(256))
let blue = Double(arc4random_uniform(256))
let color = UIColor(red: CGFloat(red/255), green: CGFloat(green/255), blue: CGFloat(blue/255), alpha: 1)
colors.append(color)
}
pieChartDataSet.colors = colors
chartView.data = pieChartData
}
Have I missed out something? Your second eye would be highly appreciated.

Answer 1

You have changed x & y values and hence index is coming as your pie chart's value. Also, please use PieChartDataEntry.
(working code on my box)
override func viewDidLoad() {
super.viewDidLoad()
let days = ["Mo", "Tu", "Wed", "Thur", "Fri", "Sat", "Sun"]
let gross = [11.00, 90.95, 250.00, 40.90, 60.88, 99.99, 25.00]
setChart(days: days, gross: gross)
}
func setChart(days: [String], gross: [Double]) {
var dataEntries: [ChartDataEntry] = []
for i in 0..<days.count {
let dataEntry = PieChartDataEntry(value : gross[i], label : days[i])
dataEntries.append(dataEntry)
}
let pieChartDataSet = PieChartDataSet(values: dataEntries, label: "Gross Income")
pieChartDataSet.sliceSpace = 2.0
let pieChartData = PieChartData(dataSets: [pieChartDataSet])
var colors: [UIColor] = []
for _ in 0..<days.count {
let red = Double(arc4random_uniform(256))
let green = Double(arc4random_uniform(256))
let blue = Double(arc4random_uniform(256))
let color = UIColor(red: CGFloat(red/255), green: CGFloat(green/255), blue: CGFloat(blue/255), alpha: 1)
colors.append(color)
}
pieChartDataSet.colors = colors
pieChartView.data = pieChartData
}
Try this and let me know.
