I switched to swift 3 and I am now struggling to get my chart data shown again. When I use it like that, I just see an empty chart. I think some initializers changed?
I am using the Swift-3.0 branch.
@IBOutlet weak var lineChartView: LineChartView!
override func viewDidLoad() {
for x in data {
...
let dataSet = LineChartDataSet(yVals: dataEntries, label: player.getName())
lineChartData.addDataSet(dataSet)
}
lineChartView.data = lineChartData
}
They changed the way, how is data constructed. Enclosed please find following sample:
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
let dollars1 = [20.0, 4.0, 6.0, 3.0, 12.0, 16.0, 4.0, 18.0, 2.0, 4.0, 5.0, 4.0]
let months = ["Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec"]
// 1 - creating an array of data entries
var yValues : [ChartDataEntry] = [ChartDataEntry]()
for i in 0 ..< months.count {
yValues.append(ChartDataEntry(x: Double(i + 1), y: dollars1[i]))
}
let data = LineChartData()
let ds = LineChartDataSet(values: yValues, label: "Months")
data.addDataSet(ds)
self.lineChartView.data = data
}
