Sub ChartSize()
'Setting the sizes of the selected chart in mm
Dim ErrMsg As String, MB As Long
'PointSize is a scale coefficient – can be adjusted
Const PointSize = 2.83, TMB = "Chart size"
On Error GoTo NoSelection
Set S = Selection.Parent
'If something other than the chart is selected
If S.Type < -4169 Then ErrMsg = "No chart": GoTo ErrExit
'Default sizes can be adjusted
ChartHeight = InputBox("Height /mm", TMB, 85)
If ChartHeight = "" Then Exit Sub
ChartWidth = InputBox("Width /mm", TMB, 100)
If ChartWidth = "" Then Exit Sub
'If the input is wrong
ErrMsg = "No correct object"
On Error GoTo ErrExit
S.Parent.Height = ChartHeight * PointSize
S.Parent.Width = ChartWidth * PointSize
On Error GoTo 0
Exit Sub
NoSelection:
ErrMsg = "No object"
ErrExit:
MB = MsgBox(ErrMsg & " was selected", vbCritical, TMB)
On Error GoTo 0
End Sub

Try using the ChartObject.Height property. I haven't
tested it, but the help
files say...
This example sets the height of the embedded chart.

Worksheets("Sheet1").ChartObjects(1).Height = 288Hope
that helps

How do you set the size of an embedded chart? I tried

sub foo()


Charts.Add

...........

ActiveChart.ChartArea.Height = 200

..........

end sub

but .height is read-only. Also tried using .Shapes, but
I
need the name of the shape (??) . Thanks
