各位先進大哥晚安！
小弟是ios app新手，正在撰寫一簡單app， 顯示api的json資料
目前遇的問題是，想要在view中顯示json資料使用折線圖（line chart)的方式呈現

首先，這是我的json格式

{
TH_5min: [
{
Data: "2019-02-23T00:00:00",
Time: "11:00:00",
XTP_A: 10.5, //溫度1
XHP_A: 11.5, //濕度1
XTP_B: 33.5,
XHP_B: 44.6,
XTP_C: 88.9,
XHP_C: 66.6,
XTP_D: 77.9,
XHP_D: 99.6,
XTP_E: 87.87,
XHP_E: 66.66
},
{
Data: "2019-02-23T00:00:00",
Time: "11:05:00",
XTP_A: 55.2,  //溫度1
XHP_A: 44.3,  //濕度1
XTP_B: 66.6,
XHP_B: 77.87,
XTP_C: 87.77,
XHP_C: 87.87,
XTP_D: 8.87,
XHP_D: 78.78,
XTP_E: 87.78,
XHP_E: 87.87
}
]
}

這是我讀取json資料並且儲存的格式

private var th_5mins = [Th_5min]() //將api 回傳json格式的陣列宣告成變數
@objc func getlatestTh_5min(){
        guard let th_5minUrl = URL(string: kivaLoanURl) else{
            return
        }
        let request = URLRequest(url: th_5minUrl)
        let task = URLSession.shared.dataTask(with: request, completionHandler: {(data,response,error) -> Void in
            if let error = error {
                print(error)
                return
            }
            if let data = data {
                self.th_5mins = self.pardrJsonData(data: data)
            }
        })
        task.resume()
    }
    func pardrJsonData(data: Data) -> [Th_5min]{
        var th_5mins = [Th_5min]()
        do {
            let jsonResult = try JSONSerialization.jsonObject(with: data, options: JSONSerialization.ReadingOptions.mutableContainers) as? NSDictionary
            let jsonTh_5mins = jsonResult?["TH_5min"] as! [AnyObject]
            for jsonTh_5min in jsonTh_5mins{
                var th_5min = Th_5min()
                th_5min.Data = jsonTh_5min["Data"] as! String
                th_5min.Time = jsonTh_5min["Time"] as! String
                th_5min.XTP_A = jsonTh_5min["XTP_A"] as! Double
                th_5min.XHP_A = jsonTh_5min["XHP_A"] as! Double
                th_5mins.append(th_5min)
            }        }catch{
                print(error)
        }
        return th_5mins
    }
}

以下是我目前實作line chart的方法

  override func viewDidLoad() {
        super.viewDidLoad()
        getlatestTh_5min()
        //創建折線圖組件對象
        chartView = LineChartView()
        chartView.frame = CGRect(x: 20, y: 80, width: self.view.bounds.width - 40,height: 300)
        self.view.addSubview(chartView)
        //產生第一條折線圖數據
        var dataEntries1 = [ChartDataEntry]()
        for i in 0...5 {
            let y = Th_5min().XTP_A
            let entry = ChartDataEntry.init(x: Double(i), y: Double(y))
            dataEntries1.append(entry)
        }
        let chartDataSet1 = LineChartDataSet(entries: dataEntries1, label: "溫度")
        //產生第二條折線圖數據
        var dataEntries2 = [ChartDataEntry]()
        for i in 0..<8 {
            let y = arc4random()%100
            let entry = ChartDataEntry.init(x: Double(i), y: Double(y))
            dataEntries2.append(entry)
        }
        let chartDataSet2 = LineChartDataSet(entries: dataEntries2, label: "濕度")
        //目前折線圖有兩條折現
        let chartData = LineChartData(dataSets: [chartDataSet1, chartDataSet2])
        //顯示折線圖數據
        chartView.data = chartData
    }

以下是成果

目前的成果只有第二條線成功顯示，但是不是我要的數據，我只有隨機產生值才有辦法顯示數據，第一條不管怎麼嘗試，json資料始終丟不到圖表裡，我想實作的是把api所有抓取到的資料（溫度1、濕度1)都丟到linechart裡去，一條顯示溫度一條顯示濕度，並且在上方X軸部分顯示json的Time，但目前連怎麼把json丟到圖表中都不知道該怎麼做，麻煩各位大哥幫忙指點方向了！
