CombinedChart and data

[Magiguigui]

What did you do?

I tried to create a CombinedChartView filled with one LineChart and one BarChart

What did you expect to happen?

Have a view with both chart

What happened instead?

No data were drawn until I setted manually the data to CombinedChartData

Charts Environment

Using Charts (3.2.2)
Using Xcode 10.1
Using Swift 4.2
Using iOS 12.1

Demo Project

var dataEntries1 = [ChartDataEntry]()
var dataEntries2 = [BarChartDataEntry]()

for (index, vals) in content.enumerated() {
    dataEntries1.append(ChartDataEntry(x: Double(index), y: Double(vals.$1)))
    dataEntries2.append(BarChartDataEntry(x: Double(index), y: Double(vals.$2)))
}

let dataSet1 = LineChartDataSet(values: dataEntries1, label: "Distance (km)")
    dataSet1.axisDependency = .left

    dataSet1.circleRadius = 5
    dataSet1.lineWidth = 2.0
    dataSet1.setColor(UIColor.orange.withAlphaComponent(0.5))
    dataSet1.setCircleColor(UIColor.orange)

    dataSet1.fillAlpha = 65 / 255.0

let dataSet2 = BarChartDataSet(values: dataEntries2, label: "Elevation (m)")
    dataSet2.axisDependency = .right

// Work
let data = CombinedChartData()
    data.lineData = LineChartData(dataSet: dataSet1)
    data.barData = BarChartData(dataSet: dataSet2)

// Doesn't work
let data = CombinedChartData(dataSets: [dataSet1, dataSet2])

self.chart.data = data
