Ios 烛台。Swift 2.2

我正在尝试使用图表库（）创建烛台KChart。我有以下代码：

func setChart(xValues: [String], valuesCandleChart: [Double]) {
    barChartView.descriptionText = ""
    barChartView.noDataText = "You need to provide data for the chart."

    var yValsCandleChart : [CandleChartDataEntry] = [CandleChartDataEntry]()
    for i in 0..<xValues.count {

        yValsCandleChart.append(ChartDataEntry(value: valuesCandleChart[i], xIndex: i))
    }
    let candleChartDataSet = LineChartDataSet(yVals: yValsCandleChart, label: nil)
    let data: CombinedChartData = CombinedChartData(xVals: xValues)
    data.candleData = CandleChartData(xVals: xValues, dataSets: [candleChartDataSet]
    barChartView.data = data
    barChartView.leftAxis.customAxisMin = 0   
}

func setChart(xValues: [String], valuesCandleChart: [[Double]]) {
    var yValsCandleChart : [CandleChartDataEntry] = [CandleChartDataEntry]()

    for i in 0..<xValues.count {
        print(" yValsCandleChart = \(valuesCandleChart[i])")
        yValsCandleChart.append(CandleChartDataEntry(xIndex: i, shadowH: valuesCandleChart[i][0], shadowL: valuesCandleChart[i][1], open: valuesCandleChart[i][2], close:  valuesCandleChart[i][0]))
    }

    let candleChartDataSet = CandleChartDataSet(yVals: yValsCandleChart, label: "test")


    let data: CombinedChartData = CombinedChartData(xVals: xValues)
    data.candleData = CandleChartData(xVals: xValues, dataSets: [candleChartDataSet])

}

override func viewDidLoad() {
    super.viewDidLoad()

let xValues = ["Jan","Feb"]
    let yValues: [[Double]] = [[10.0,1.5,5.5,3.6],[20.0,3.0,11.0,7.2]]

    setChart(xValues, valuesCandleChart: yValues)
}

func集合图表（xValues:[String]，valuesCandleChart:[Double]）{
barChartView.descriptionText=“”
barChartView.NodeataText=“您需要为图表提供数据。”
变量yValsCandleChart:[CandleChartDataEntry]=[CandleChartDataEntry]（）
对于0中的i..您使用了错误的数据集和条目类，请使用
CandleChartDataSet
和
CandleChartDataEntry

您必须使用它的init方法

CandleChartDataEntry（xIndex:Int，shadowH:Double，shadowL:Double，open:Double，close:Double）

var yValsCandleChart:[CandleChartDataEntry]=[CandleChartDataEntry]（）
对于0中的i..is
ChartDataEntry
是
CandleChartDataEntry
的超类吗？它们之间的任何关系？我不确定。我在使用条形图和折线图时使用了“ChartDataEntry”。当我使用“CandleChartDataEntry”时，我得到一个错误“无法使用参数列表类型为“CandleChartDataEntry”的初始化器”（value:Double，xIndex:Int）“我认为您使用的是第三方库？您需要查看该库的文档，看看数据对象的类层次结构是什么，以及每种类型的图表需要传递什么。（您可能需要编辑您的问题，以便“我正在尝试使用上提供的开源库
CandleStickChart
创建一个CandleStickChart。”@Duncac是的，我正在使用图表库（danielgindib），感谢tipI，我现在收到错误“无法使用类型为“（value:Double，index:Int）”的参数列表调用类型为“CandleChartDataEntry”的初始化器”“ValueScanneChart=[5.0,7.0,1.0,1.0,2.0,3.0,11.0,7.0,7.0,5.0]，这是正确的格式吗？这是因为它不继承超类的init（值：Double，索引：Int）。答案已更新。您应该使用CandleChartDataEntry的init方法。您好，我仍然收到错误消息。”无法使用类型为“（xIndex:Int，shadowH:Double，shadowL:Double，open:Double，close:Double）的参数列表调用类型为“CandleChartDataEntry”的初始化器。类型“。我已用以下错误消息更新了我的代码。您完全不了解什么是swift函数参数。修复错误是您的责任。我已经提供了足够的信息。代码已更新。请慢慢从演示中了解所有信息。我无法提供更多帮助。”。
