I was looking for an answer to creating a chart from merged cells. After searching and not finding an answer I came across the Union method.

This sub creates a chart for a series of two merged cells expanding across the whole worksheet apart for the first two cells

Sub subCreateChart()
'This sub creates a chart for merged cells taking the information from the cell listed
'eg the two merged cells C37 and D37 the Excel address is C37 that holds the data.
Dim rngAvg As Range
Dim rngTemp As Range
Dim i As Integer

For i = 3 To 253 Step 2

Set rngTemp = Range(Cells(37, i), Cells(39, i)) 'Set the first and subsequent merged cells as a range.
If i = 3 Then
Set rngAvg = rngTemp 'set the first selected range to an accumulating range
Else
Set rngAvg = Union(rngAvg, rngTemp) 'after the first range has been assigned to rngAvg
'add all over ranges by looping through the required data.
End If
Next i

Charts.Add
ActiveChart.ChartType = xlLine

ActiveChart.SetSourceData rngAvg, PlotBy:=xlRows 'when collection is complete use the accuumulated
'range to create chart.
ActiveChart.DisplayBlanksAs = Excel.XlDisplayBlanksAs.xlInterpolated
ActiveChart.Location Whe=xlLocationAsObject, Name:="Sheet1"
With ActiveChart
.HasTitle = False
.Axes(xlCategory, xlPrimary).HasTitle = False
.Axes(xlValue, xlPrimary).HasTitle = False
End With
End Sub

Merged cells are to be avoided at all costs.
They can be used for column heading but for little else.

merged cells and creating charts
I have tried to create a chart with data that is in merged cells where I have
put in a formula to calculate the average of 4 cells in the row above. When I
create the chart, it recognizes all 4 of the merged cells. So the graph has 4
spaces for the data for each number I am trying to plot. I just got 2007
version and do not recall this problem at all in 2003 version

Thank you for adding yet another example to the countless demonstrations
(listed in the archives of these Excel newsgroups) of why merged cells
should be avoided like the plague.
We keep advising people, but they keep shooting themselves in the foot by
using merged cells when there are usually much better alternatives (such as
the alignment option to "Center across selection").
