我正在尝试移动当前显示的数据范围，阅读文档后，似乎可以使用moveViewToX函数将视图左侧移动到给定的x值。
我做了一个测试代码，其中包含1个带按钮的视图。当视图加载到模拟器中时，图形正确显示。当单击按钮时，它调用moveViewToX。但是，当我单击按钮时，什么也没发生（当单击按钮时，打印文本打印到控制台，图形视图保持不变）。

import Charts
import UIKit

class ViewController: UIViewController {

override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view, typically from a nib.

    //Setup Test Chart
    self.lineChartView.data = LineChartData(dataSet: lineChartDataSet())

}

fileprivate func lineChartDataSet() -> LineChartDataSet {
    var dataEntries = [ChartDataEntry]()
    dataEntries.append(ChartDataEntry(x: 1, y: 2))
    dataEntries.append(ChartDataEntry(x: 3, y: 5))
    dataEntries.append(ChartDataEntry(x: 5, y: 10))
    dataEntries.append(ChartDataEntry(x: 6, y: 2))
    dataEntries.append(ChartDataEntry(x: 10, y: 15))
    dataEntries.append(ChartDataEntry(x: 12, y: 7))
    dataEntries.append(ChartDataEntry(x: 20, y: 10))
    dataEntries.append(ChartDataEntry(x: 30, y: 15))

    return LineChartDataSet(values: dataEntries, label: "Test Data")
}

@IBAction func buttonClick(_ sender: UIButton) {
    print("Button clicked")
    self.lineChartView.moveViewToX(5)
}
@IBOutlet weak var lineChartView: LineChartView!
}
