如何使用IOSChart显示ChartValueSelected的另一个ViewController？

// ChartViewController.swift

import UIKit
import Charts

class ChartViewController: UIViewController, ChartViewDelegate {
    
    @IBOutlet weak var chartView: BarChartView!
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        // 设置代理
        chartView.delegate = self
        
        // 设置图表数据等...
    }
    
    // ChartViewDelegate方法
    func chartValueSelected(_ chartView: ChartViewBase, entry: ChartDataEntry, highlight: Highlight) {
        // 获取选中的数据
        let selectedValue = entry.y
        
        // 创建ChartDetailViewController实例
        let chartDetailVC = ChartDetailViewController()
        
        // 将选中的数据传递给ChartDetailViewController
        chartDetailVC.selectedValue = selectedValue
        
        // 使用导航控制器将ChartDetailViewController推入导航堆栈
        navigationController?.pushViewController(chartDetailVC, animated: true)
    }
}

// ChartDetailViewController.swift

import UIKit

class ChartDetailViewController: UIViewController {
    
    var selectedValue: Double = 0.0
    
    @IBOutlet weak var valueLabel: UILabel!
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        // 在界面上显示选中的数据
        valueLabel.text = "\(selectedValue)"
    }
}
