ios-charts缺少PieChart的标签(传说)

概述我正在尝试从ios-charts库实现饼图一切都很好,但是我从图中遗漏了传说 – 这是我的代码 – // This is the delegate method for creating data for chart func offDaysDidLoaded(controller: DataModel,chartArray:[PFObject]) { 我正在尝试从ios-charts库实现饼图一切都很好,但是我从图中遗漏了传说 –

这是我的代码 –

// This is the delegate method for creating data for chart        func offDaysDIDLoaded(controller: DataModel,chartArray:[PFObject]) {                let formatter = NSDateFormatter()                formatter.dateFormat = "MMM"                dataDict = [:]                for od in chartArray {                    let date = od["Date"] as! NSDate                    let month = formatter.stringFromDate(date)                    if self.dateDict.indexForKey(month) != nil {                        self.dateDict[month]! += 1.0                    }else{                        self.dateDict.updateValue(1.0,forKey: month)                    }                }                let dataPointArray = Array(dateDict.keys)                let valuesArray = Array(dateDict.values)                pIEChartVIEw.data = nil                pIEChartVIEw.backgroundcolor = UIcolor.graycolor()                setChart(dataPointArray,values: valuesArray)            }func setChart(dataPoints: [String],values: [Double]) {    var dataEntrIEs: [ChartDataEntry] = []    for i in 0..<dataPoints.count {        let dataEntry = ChartDataEntry(value: values[i],xIndex: i)        dataEntrIEs.append(dataEntry)    }    let pIEChartDataSet = PIEChartDataSet(yVals: dataEntrIEs,label: "Months")    let pIEChartData = PIEChartData(xVals: dataPoints,dataSet: pIEChartDataSet)    pIEChartData.setDrawValues(false)    pIEChartVIEw.data = pIEChartData    pIEChartVIEw.animate(xAxisDuration: NSTimeInterval(5))    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}

我在here中看到了类似的问题并且构建和运行,问题中使用的饼图也没有在图表下方显示任何图例.任何帮助或指针将非常感激.

谢谢
