how to add data label to bubble chart in excel


Hi I want to add customize data label to my bubble chart. my code is below. at the moment data label refer to XValues. I would like my data label fill with bubble size. would u mind help me how I can customize below code?

I tried to add .DataLabel.Text = "txt" but I received below error: Run-time error '438':Object doesn't support this property or method

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

End Sub

My input sample:

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

Solution

  • DataLabel.Text is a method for a Point, not the NewSeries

    This code:

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

    ...attempts to label the series, and fails.

    Recognizing this code as being from another famous example of "multi-series Bubble Charts", it is a logical assumption that we only need to handle 1 data point per series, which makes the following code the solution:

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