Hi
it is. But maybe give some more details what you're trying to achieve
exactly

Phil,

I may not be understanding your question but would a macro like the example
below do?  It extracts the text in the first series data label to an variable
of the integer type and then references that variable in a formula in cell
A1.  In this example, the formula would look like "= 6 + your label value +
4".  Click on your chart to activate it and then run the macro.  If it works
for you, it would need to be modified to your specs:

Sub DataLabelTextToFormula()
   Dim Cht As Chart
   Dim Val As Integer
   Set Cht = ActiveChart
   Cht.SeriesCollection(1).ApplyDataLabels Type:=xlDataLabelsShowValue
   Val = Cht.SeriesCollection(1).Points(1).DataLabel.Text
   Worksheets("Sheet1").Range("A1").Formula = "=6+" & Val & "+4"
End Sub

Other than that, you can always direct reference the data source in your
formula as it is the same source for the data label.
