I have a bubble chart (see attached file). I want to display the split between "complex" and  "standard" percentages (Column "F" and "G").  Is it possible to display pie charts inside this bubble charts?

It's not possible to do that. I would suggest that you make a pie chart and put on top of the bubble chart, on a corner, like a "zoom" of the data to show the split...that's the only solution I can think of...

Hello,

You could create your pie charts separately, copy the pie charts as pictures and use these pictures to format each individual bubble with a picture fill from Clipboard.

This will retain the pie chart when the bubble changes position.

It will also grow or shrink with the bubble size.

But the image fills within the bubble chart are not dynamic, so if the pie charts change, you will need to re-do the image fill for the bubbles.

There's probably a way to store the images to disk and have them updated automatically via VBA and then connect each bubble with a specific image on disk.

See attached file for an implementation of the manual approach created with Excel 2010

Thank you cslarsen,

it is the right solution.  I don't think I am getting the code right though. Could you help me out?

This my code (the updated file is attached:

Sub PieMarkers()
     
    Dim chtMarker As Chart
    Dim chtMain As Chart
    Dim intPoint As Integer
    Dim rngRow As Range
    Dim lngPointIndex As Long
     
    Application.ScreenUpdating = False
     ' reference to pie chart
    Set chtMarker = ActiveSheet.ChartObjects("chtPieMarker").Chart
     ' reference to chart that pie markers will be applied to
    Set chtMain = ActiveSheet.ChartObjects(1).Chart
     
     ' pie chart data which will be processed by rows
    For Each rngRow In Range("A1:D6").Rows
         ' assign new values to pie chart
        chtMarker.SeriesCollection(1).Values = rngRow
         ' copy pie
        chtMarker.Parent.CopyPicture xlScreen, xlPicture
         ' paste to appropriate data point
        lngPointIndex = lngPointIndex + 1
        chtMain.SeriesCollection(1).Points(lngPointIndex).Paste
    Next
     
     ' release objects
    Set chtMarker = Nothing
    Set chtMain = Nothing
    Application.ScreenUpdating = False
     
End Sub

Hi f,
Ok, you have switched the name of the marker-chart and the bubble chart
(Chart 3 in the original example.)

Check this example
