Berthica,
Tushar has a good point. Hopefully these macros will help too:
If you're working with embedded charts, this will give you the name of each
chart on the worksheet. You may need to add a different destination range.
Sub ListChartNames()
Dim Cht As ChartObject
Dim Rng As Range
Set Rng = ActiveSheet.Range("A1")
For Each Cht In ActiveSheet.ChartObjects
Rng.Value = Cht.Chart.Parent.Name
Set Rng = Rng.Offset(1, 0)
Next Cht
End Sub
This macro will rename each embedded chart in a sequential fashion if
needed. If you have a lot of charts and need to create some kind of logic
for naming them all, maybe this will help.
Sub NameSequentialCharts()
Dim Cht As ChartObject
Dim i As Integer
i = 1
For Each Cht In ActiveSheet.ChartObjects
Cht.Chart.Parent.Name = "Chart" & i
i = i + 1
Next Cht
End Sub
I forgot to mention before, for the first set of macros to work you much
activate the embedded chart first.
