Bubble Charts

[winlefu]

Hi, hope someone can help me I was using the following VBA cod
(http://blogs.msdn.com/b/tomholl/arch...-in-excel.aspx) to graph
bubble chart in excel but the problem is that the small bubble got hid
by a larger bubble after run the code.

Please help

Regards,

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 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)
End With

Next
bubbleChart.Chart.SetElemen
(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
