如何在excel中为气泡图添加数据标签

Question

嗨，我想将自定义数据标签添加到我的气泡图中。我的代码在下面。目前数据标签指的是XValues。我希望我的数据标签填充气泡大小。你介意帮我如何自定义下面的代码吗？

我尝试添加.DataLabel.Text="txt"，但收到以下内容错误：运行时错误"438"：对象不支持此属性或方法

Public Sub CreateMultiSeriesBubbleChart()
If (Selection.Columns.Count <> 4 Or Selection.Rows.Count < 3) Then
    MsgBox "Selection must have 4 columns and at least 2 rows"
    Exit Sub
End If
Dim red, green, blue As Integer

Dim bubbleChart As ChartObject
Set bubbleChart = ActiveSheet.ChartObjects.Add(Left:=Selection.Left, Width:=600, Top:=Selection.Top, Height:=400)
bubbleChart.Chart.ChartType = xlBubble
Dim r As Integer
For r = 2 To Selection.Rows.Count
    With bubbleChart.Chart.SeriesCollection.NewSeries
        .Name = "=" & Selection.Cells(r, 1).Address(External:=True)
        .XValues = Selection.Cells(r, 2).Address(External:=True)
        .Values = Selection.Cells(r, 3).Address(External:=True)
        .BubbleSizes = Selection.Cells(r, 4).Address(External:=True)
        .Format.Fill.Solid
        .Format.Fill.ForeColor.RGB = RGB(61, 161, 161)
     '   .DataLabel.Text = "txt"
    End With
Next
bubbleChart.Chart.SetElement (msoElementPrimaryCategoryAxisTitleAdjacentToAxis)
bubbleChart.Chart.Axes(xlCategory, xlPrimary).AxisTitle.Text = "=" & Selection.Cells(1, 2).Address(External:=True)
bubbleChart.Chart.SetElement (msoElementPrimaryValueAxisTitleRotated)
bubbleChart.Chart.Axes(xlValue, xlPrimary).AxisTitle.Text = "=" & Selection.Cells(1, 3).Address(External:=True)
bubbleChart.Chart.SetElement (msoElementPrimaryCategoryGridLinesMajor)
bubbleChart.Chart.Axes(xlCategory).MinimumScale = 0

结束子

我的输入样本：

Label          Hour Day count
01-SUNDAY       14  1   1
01-SUNDAY       19  1   1
02-MONDAY       12  2   1
02-MONDAY       13  2   1
02-MONDAY       14  2   2
02-MONDAY       16  2   2

Answer 1

在不使用VBA的情况下，右键单击气泡并选择"添加数据标签"。然后，在数据标签上单击鼠标右键，然后单击"设置数据标签格式"。在"标签选项"下，选择"来自单元格的值"，然后指定包含要使用的标签的单元格。

Answer 2

DataLabel.Text是Point的方法，而不是NewSeries

此代码：

For r = 2 To Selection.Rows.Count
    With bubbleChart.Chart.SeriesCollection.NewSeries
        [...]
        .DataLabel.Text = "txt"
    End With 
Next

尝试标记该系列，但失败。

认识到这段代码来自另一个著名的"多系列气泡图"示例，我们合理地假设每个系列只需要处理1个数据点，这使得以下代码成为解决方案：

For r = 2 To Selection.Rows.Count
    With bubbleChart.Chart.SeriesCollection.NewSeries
        [...]
        .Points(1).HasDataLabel = True
        .Points(1).DataLabel.Text = "txt"
    End With 
Next
