Question

我正在尝试动态地将多个系列添加到折线图中。我事先不知道有多少系列，所以它需要是动态的。我提出但不起作用的是以下内容：

工作表ActiveSheet（或Sheets（“Data”））具有从C14到Cend的行包含来自E14的XValues和列：Eend直到R14：Rend其中“end”标记由C列确定的最后一行数据。系列名称存储在第9行。对于所有系列，XValues都是相同的。

我的一个大问题是，我找不到将所有数据列作为系列动态添加到我的图表中的方法以及相应的名称。我不是VBA的专家所以请善待。我已经阅读了各种来源并尝试了许多脚本，似乎都没有。对象目录有点帮助，但我的问题仍然存在。

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

感谢您的帮助。我解决了这个问题。似乎我已经以某种方式完全搞砸了细胞范围的符号。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并没有多大帮助，因为Excel会尝试自动为所有系列找到正确的范围并添加它们，从而导致完全混乱的图表。更好的方法是使用

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

因为这会创建一个完全空的图表，您可以添加自己的系列

以下是感兴趣的人的完整且有效的代码：

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

你可以迭代范围并继续添加更多系列

Excel VBA脚本可以动态地将系列添加到图表中
