IOS Swift Charts3.0：如何添加Xvals

在Charts2.3中我們可以使用下面的代碼來添加數據。IOS Swift Charts3.0：如何添加Xvals

代碼：

let chartDataSet = LineChartDataSet(yVals: dataEntries, label: "Units Sold") 
let chartData = LineChartData(xVals: months, dataSet: chartDataSet)

但在Charts3.0，我無法找到該參數的幾個月添加到我的線型圖

代碼：

var months: [String]! 
months = ["Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec"] 
let unitsSold = [20.0, 4.0, 6.0, 3.0, 12.0, 16.0, 4.0, 18.0, 2.0, 4.0, 5.0, 4.0] 
setChart(dataPoints: months, values: unitsSold) 

func setChart(dataPoints: [String], values: [Double]) { 
     var dataEntries: [ChartDataEntry] = [] 
     for i in 0..<dataPoints.count { 
      let dataEntry = ChartDataEntry(x: Double(i), y: values[i]) 
      dataEntries.append(dataEntry) 
     } 
     let lineChartDataSet = LineChartDataSet(values: dataEntries, label: "test") 

     let lineChartData = LineChartData() 
     lineChartData.addDataSet(lineChartDataSet) 
    self.lineChartView.chartDescription?.text = "TestLinechart" 
    }

對於下面的函數您可以設置線路數據的數據數據

lineChartView.xAxis.valueFormatter = IndexAxisValueFormatter(values: dataPoints) 

    lineChartView.xAxis.granularity = 1.0

希望這會幫助你！
