Charts 快捷键图表到共享表

我通过以下方式在SwiftUI中使用图表：

我只想做一个屏幕特定部分的共享表

图表是这样显示的

Bar(entries: [
      
        BarChartDataEntry(x: 1, y: 1),
        BarChartDataEntry(x: 2, y: 1),
        BarChartDataEntry(x: 3, y: 1),
        BarChartDataEntry(x: 4, y: 1),
        BarChartDataEntry(x: 5, y: 1)

    ])

那么，我如何才能更改为图像以便共享它们呢？我不想分享整个页面，只想分享每个图表

谢谢。

这是我的工作。股票是标准的东西。该图表来自上述网站

这非常有帮助：

警告；如果在滚动视图中存在问题
