excel - Export chart as image - with click of a button

Question

I'm trying to create a button that would export a chart in sheet "Graphs" as a jpeg file. This is the code I have, however it keeps on showing this error:

runtime error 424: object required

Specifically for this:

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

And here's the code

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

Thanks everyone!

Is this what you are trying?

Also if you are trying to save it as jpg then why a png filter? I have changed "myChart.jpg" to "myChart.png". Change as applicable.

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
