自从我有空以来，我为您创建了一个基本版本. :)

Since I was free, I created a basic version for you. :)

要求:在用户表单中显示图表

Requirement: Show Chart in a Userform

逻辑:

1. 创建一个用户窗体，并在其中放置一个图像控件和一个命令按钮.
2. 确定图表的数据范围
3. 添加临时表
4. 在临时表中创建图表
5. 将图表作为bmp导出到用户的临时目录中
6. 使用该图像加载图像控件

假设:

我假设您图表的数据范围在[Sheet1]中，如下所示.请相应地修改代码.

I am assuming that your chart's data range is in [Sheet1] and look like this. Please amend the code accordingly.

准备用户表单

代码

此代码在用户表单代码区域中.我已经注释了该代码，以便您在理解它时不会有任何问题.如果还是这样，请发回.

This code goes in the userform code area. I have commented the code so that you will not have any problem understanding it. Still if you so, post back.

Private Declare Function GetTempPath Lib "kernel32" Alias "GetTempPathA" _
(ByVal nBufferLength As Long, ByVal lpBuffer As String) As Long

Private Const MAX_PATH As Long = 260

Private Sub CommandButton1_Click()
    Dim ws As Worksheet
    Dim wsTemp As Worksheet
    Dim rng As Range
    Dim oChrt As ChartObject

    '~~> Set the sheet where you have the charts data
    Set ws = [Sheet1]

    '~~> This is your charts range
    Set rng = ws.Range("A1:B3")

    '~~> Delete the temp sheeet if it is there
    Application.DisplayAlerts = False
    On Error Resume Next
    ThisWorkbook.Sheets("TempOutput").Delete
    On Error GoTo 0
    Application.DisplayAlerts = True

    '~~> Add a new temp sheet
    Set wsTemp = ThisWorkbook.Sheets.Add

    With wsTemp
        '~~> Give it a name so that we can delete it as shown above
        '~~> This is just a precaution in case `wsTemp.Delete` fails below
        .Name = "TempOutput"

        '~~~> Add the chart
        Set oChrt = .ChartObjects.Add _
            (Left:=50, Width:=300, Top:=75, Height:=225)

        '~~> Set the chart's source data and type
        '~~> Change as applicable
        With oChrt.Chart
            .SetSourceData Source:=rng
            .ChartType = xlXYScatterLines
        End With
    End With

    '~~> Export the chart as bmp to the temp drive
    oChrt.Chart.Export Filename:=TempPath & "TempChart.bmp", Filtername:="Bmp"

    '~~> Load the image to the image control
    Me.Image1.Picture = LoadPicture(TempPath & "TempChart.bmp")

    '~~> Delete the temp sheet
    Application.DisplayAlerts = False
    wsTemp.Delete
    Application.DisplayAlerts = True

    '~~> Kill the temp file
    On Error Resume Next
    Kill TempPath & "TempChart.bmp"
    On Error GoTo 0
End Sub

'~~> Function to get the user's temp path
Function TempPath() As String
    TempPath = String$(MAX_PATH, Chr$(0))
    GetTempPath MAX_PATH, TempPath
    TempPath = Replace(TempPath, Chr$(0), "")
End Function

输出:

当您运行用户窗体并按命令按钮时，您将在用户窗体中看到该图像.

When you run the userform and press the command button, you will see the image populate in the userform.
