Andy, I raise my glass to you as this worked! I assume this code takes a
range and converts it to R1-style notation? Thanks to you (and Peter) and
have a blessed day. Giorgio

Try,

I still get a debug error on the line ".BubbleSizes = rng4". The bubble sizes
are in percentages, which when I add the data manually, works. I have also
tried changing the data to comma format numbers and still the code stops at
this line.

Assuming you are putting valid data in your range variables, try changing
the second part of your routine as follows -

With ActiveSheet.ChartObjects("BubbleChart").Chart
.SeriesCollection.NewSeries
With .SeriesCollection(.SeriesCollection.Count)
.XValues = rng2
.Values = rng3
.Name = rng
.BubbleSizes = rng4
End With
End With

I need to automate the process of adding one bubble to a bubble chart.

Most

of the code works fine, however, I cannot define the size of the bubble
correctly as it seems that I must use R1-style notation. Any assistance

would

be greatly appreciated.

Sub AddBubble()
Dim rng As Variant
Dim rng2 As Variant
Dim rng3 As Variant
Dim rng4 As Variant

Set rng = ActiveCell
ActiveCell.Offset(0, 1).Range("A1").Select
Set rng2 = ActiveCell
ActiveCell.Offset(0, 2).Range("A1").Select
Set rng3 = ActiveCell
ActiveCell.Offset(0, 1).Range("A1").Select
Set rng4 = ActiveCell

ActiveSheet.ChartObjects("BubbleChart").Activate
ActiveChart.ChartType = xlBubble
ActiveChart.SeriesCollection.NewSeries
ActiveChart.SeriesCollection(2).XValues = rng2
ActiveChart.SeriesCollection(2).Values = rng3
ActiveChart.SeriesCollection(2).Name = rng
ActiveChart.SeriesCollection(2).BubbleSizes = rng4
ActiveChart.ChartType = xlBubble
End Sub
