vba - 在 VBA 中使用动态命名范围进行散点图标注

Question

我正在尝试制作一个宏，它将散点图上的数据标签更改为每个点的标题。例如：

_{（来源：wiseowl.co.uk）}

在这种情况下，我希望数据标签显示电影标题。我使用的代码来自这个网站，但是我的散点图有两个系列的数据。我想使用动态命名范围来告诉宏名称所在的单元格范围，在我的代码中，动态命名范围是 FONames 和 BONames。这是我的代码：

Sub CreateDataLabels()
'holds the entire film data series in the chart
Dim FilmDataSeries As Series
Dim FilmDataSeries2 As Series
'holds one cell at a time
Dim SingleCell As Range
'holds the full list of cells containing film names
Dim FilmList As Range
Dim FilmList2 As Range
'keeps track of which datapoint we're labelling
Dim FilmCounter As Integer
Dim FilmCounter2 As Integer
'The sheet in which the graph is on
Dim ws As Worksheet
Set ws = Worksheets("Datos Gráfico")

'set the counter to start at 1
FilmCounter = 1
FilmCounter2 = 1

'set a reference to the cells containing the list of films
Set FilmList = Range("FONames")
Set FilmList2 = Range("BONames")

'set a reference to the chart data series
Set FilmDataSeries = ws.ChartObjects(1).Chart.SeriesCollection(1)
Set FilmDataSeries2 = ws.ChartObjects(1).Chart.SeriesCollection(2)

'make sure data labels are turned on
FilmDataSeries.HasDataLabels = True
FilmDataSeries2.HasDataLabels = True

'loop over the cells in the list of films
For Each SingleCell In FilmList
    FilmDataSeries.Points(FilmCounter).DataLabel.Text = SingleCell.Value
    FilmCounter = FilmCounter + 1
Next SingleCell

For Each SingleCell In FilmList2
    FilmDataSeries2.Points(FilmCounter2).DataLabel.Text = SingleCell.Value
    FilmCounter2 = FilmCounter2 + 1
Next SingleCell

End Sub

我收到 1004 错误，指出指定的尺寸无效。当我用实际的单元格范围替换 FONames 或 BONames 时，例如。范围（“A5”，“A11”），一切正常。如何在我的代码中使用这些动态命名范围？

Answer 1

例如 ：

'---------------------------------------------------------------------------
' In order to add label at scatter graph. You must selected a graph before.
' @param void
'---------------------------------------------------------------------------
Sub add_label_on_graph()
    Dim Counter As Integer
    Dim xVals As String
    Dim reponse As Integer

    If ActiveChart Is Nothing Then
        reponse = MsgBox("Attention, vous devez au préalable sélectionner un graphique avant de lancer cette commande.", vbExclamation, "Information")
        Exit Sub
    End If

    Application.ScreenUpdating = False

    ' Récupération de la range des données que l'on stocke dans la variable xVals.
    xVals = ActiveChart.SeriesCollection(1).Formula
    xVals = Mid(xVals, InStr(InStr(xVals, ","), xVals, Mid(Left(xVals, InStr(xVals, "!") - 1), 9)))
    xVals = Left(xVals, InStr(InStr(xVals, "!"), xVals, ",") - 1)
    Do While Left(xVals, 1) = ","
        xVals = Mid(xVals, 2)
    Loop

    ' Ajoute un label à chaque point du graphique
    For Counter = 1 To Range(xVals).Cells.Count
        ActiveChart.SeriesCollection(1).Points(Counter).HasDataLabel = True
        ActiveChart.SeriesCollection(1).Points(Counter).DataLabel.text = Range(xVals).Cells(Counter, 1).Offset(0, -1).Value
    Next Counter

    Application.ScreenUpdating = True
End Sub

您的动态命名范围的定义是什么？我为 A 列定义了一个命名范围，如下所示：

=OFFSET(Sheet1!$A$1,1,0,COUNTA(Sheet1!$A:$A)-1,1)

它工作得很好。
