使用Excel VBA脚本动态添加序列到图表

Question

我正在尝试动态地向折线图中添加多个系列。我事先不知道有多少个系列，因此需要动态处理。我想到的但不起作用的方法如下：

工作表ActiveSheet（或Sheets（"Data"））从C14到Cend包含XValues和从E14：Eend到R14：Rend的列，其中“ end”表示由列C确定的最后一行数据。系列名称存储在第9行。所有系列的XValues相同。

我的主要问题是，我找不到一种方法将所有数据列动态添加到我的图表中，并带有相应的名称。我不是VBA专家，请多多关照。我已经阅读了各种来源并尝试了许多脚本，但似乎没有一个正常工作。对象目录有点帮助，但是我的问题仍然存在。

Sub MakeChart()
Dim LastColumn As Long
Dim LastRow As Long
Dim i As Integer
Dim u As Integer
Dim NameRng As String
Dim CountsRng As Range
Dim xRng As Range

    LastColumn = ActiveSheet.Cells(8, Columns.Count).End(xlToLeft).Column
    ColumnCount = LastColumn - 4
    LastRow = ActiveSheet.Range("C" & ActiveSheet.Rows.Count).End(xlUp).Row
'   Debug.Print ("Last Column: " & LastColumn & " Count: " & ColumnCount & " LastRow: " & LastRow)

    Charts.Add
    With ActiveChart
        .ChartType = xlLineMarkers
        .HasTitle = True
        .ChartTitle.Text = "Test"
    End With

    For i = 1 To ColumnCount
        u = i + 4
       NameRng = Sheets("Data").Range("R9:C" & u).Value
       Set xRng = Sheets("Data").Range("R14:C3", "R" & LastRow & ":C3")
       Set CountsRng = Sheets("Data").Range("R14:C" & u, "R" & LastRow & ":C" & u)
'      Debug.Print ("CountsRng: R14:C" & u & ", R" & LastRow & ":C" & u & " NameRng: " & NameRng & " xRng: R14:C3 , R" & LastRow & ":C3")
            ActiveChart.SeriesCollection.NewSeries
            ActiveChart.SeriesCollection(i).XValues = xRng
            ActiveChart.SeriesCollection(i).Values = CountsRng
            ActiveChart.SeriesCollection(i).Name = NameRng
    Next i

End Sub

它能工作到哪里？从哪个点开始就不能工作了？ - K_B

系列是否从系列0开始？因此SeriesCollection（i-1）？如果我没记错的话，您也可以使用With ActiveChart.SeriesCollection.NewSeries，然后在以下行中设置.XValues等。 然后用End With关闭。 - K_B

感谢你的帮助。我已经解决了这个问题。似乎我在单元格范围的表示上弄混了。你不能使用。

Set xRng = Sheets("Data").Range("R14:C3", "R" & LastRow & ":C3")

但必须使用

Set xRng = .Range(.Cells(14, 3), .Cells(LastRow, 3))

此外，使用Charts.Add并没有什么帮助，因为Excel会尝试自动查找所有系列的正确范围并将它们添加到图表中，导致图表完全混乱。更好的方法是使用

Set ChartObj = ActiveSheet.ChartObjects.Add(Left:=20, Width:=800, Top:=20, Height:=500)

这将创建一个完全空的图表，您可以向其中添加自己的系列。

以下是完整且可工作的代码，供任何有兴趣的人使用：

Sub MakeChart()
    Dim LastRow As Long
    Dim LastColumn As Long
    Dim ColumnCount As Long
    LastRow = ActiveSheet.Range("C" & ActiveSheet.Rows.Count).End(xlUp).Row
    LastColumn = ActiveSheet.Cells(8, Columns.Count).End(xlToLeft).Column
    ColumnCount = LastColumn - 4
    Debug.Print ("Last Column: " & LastColumn & " Count: " & ColumnCount & " LastRow: " & LastRow)

    Dim wsChart As Worksheet
    Set wsChart = Sheets(1)
    wsChart.Activate
    Dim ChartObj As ChartObject
    Set ChartObj = ActiveSheet.ChartObjects.Add(Left:=20, Width:=800, Top:=20, Height:=500)
    ChartObj.chart.ChartType = xlLineMarkers

    Dim i As Integer
    Dim u As Integer
    Dim NameRng As String
    Dim xRng As Range
    Dim CountsRng As Range

    For i = 1 To ColumnCount
        u = i + 4

        With Sheets("Data")
            NameRng = .Cells(9, u).Value
            Set CountsRng = .Range(.Cells(14, u), .Cells(LastRow, u))
            Set xRng = .Range(.Cells(14, 3), .Cells(LastRow, 3))
            Debug.Print "--" & i & "--" & u & "--"
            Debug.Print "x Range: " & xRng.Address
            Debug.Print "Name Range: " & .Cells(9, u).Address
            Debug.Print "Value Range: " & CountsRng.Address
        End With

        'Set ChartSeries = ChartObj.chart.SeriesCollection.NewSeries
        'With ActiveChart.SeriesCollection.NewSeries
        With ChartObj.chart.SeriesCollection.NewSeries
            .XValues = xRng
            .Values = CountsRng
            .Name = NameRng
        End With
        'Set xRng = Nothing
        'Set CountsRng = Nothing
        'NameRng = ""
    Next i

    'ChartObj.Activate
    With ChartObj.chart
        .SetElement (msoElementLegendBottom)
        .Axes(xlValue).MajorUnit = 1
        .Axes(xlValue).MinorUnit = 0.5
        .Axes(xlValue).MinorTickMark = xlOutside
        '.Axes(xlCategory).TickLabels.NumberFormat = "#,##000"
        .Axes(xlCategory).TickLabels.NumberFormat = "#,##0"
        '.Location Where:=xlLocationAsObject, Name:="Plot"
    End With

End Sub

示例代码

Sub InsertChart()

    Dim first As Long, last As Long
    first = 10
    last = 20

    Dim wsChart As Worksheet
    Set wsChart = Sheets(1)

    wsChart.Activate
    wsChart.Shapes.AddChart.Select

    Dim chart As chart
    Set chart = ActiveChart
    chart.ChartType = xlXYScatter

    ' adding series
    chart.SeriesCollection.NewSeries
    chart.SeriesCollection(1).Name = "series name"
    chart.SeriesCollection(1).XValues = "=" & ActiveSheet.Name & "!$A$" & first & ":$A$" & last
    chart.SeriesCollection(1).Values = "=" & ActiveSheet.Name & "!$B$" & first & ":$B$" & last

End Sub

您可以遍历范围并不断添加更多的系列。
