将图表导出为图像 - 只需单击按钮

我正在尝试创建一个按钮，将“图表”工作表中的图表导出为 jpeg 文件。这是我的代码，但它不断显示此错误：

运行时错误 424：需要对象

具体来说：

Set myChart = Graphs.ChartObjects(3).Name = "Chart4"

这是代码

Sub ExportChart()
    Dim myChart As Chart
    Dim myFileName As String
    Set myChart = Graphs.ChartObjects(3).Name = "Chart4"
    myFileName = "myChart.jpg"
    On Error Resume Next
    Kill ThisWorkbook.Path & "\" & myFileName
    myChart.Export Filename:=ThisWorkbook.Path & "\" & myFileName, Filtername:="PNG"
    MsgBox "OK"
    Set myChart = Nothing
End Sub

感谢大家！

这就是你正在尝试的吗？

另外，如果你想将其保存为 jpg 那么为什么要使用 png 过滤器呢？我已将“myChart.jpg”更改为“myChart.png”。根据情况进行更改。

Sub ExportChart()
    Dim objChrt As ChartObject
    Dim myChart As Chart

    Set objChrt = Sheets("Graphs").ChartObjects(3)
    Set myChart = objChrt.Chart

    myFileName = "myChart.png"

    On Error Resume Next
    Kill ThisWorkbook.Path & "\" & myFileName
    On Error GoTo 0

    myChart.Export Filename:=ThisWorkbook.Path & "\" & myFileName, Filtername:="PNG"

    MsgBox "OK"
End Sub
