Oh sorry! The ReDimTest is 3 tests. Could you please create two graphs
separately for ReDimTest1 and ReDimTest2 in

> Type TCustomType
>   m_arr(20) As Long
>   m_str As String
> End Type
> 
> Sub CustomReDim1(ByRef A() As TCustomType, newU As Long)
>   ReDim Preserve A(newU)
> End Sub
> 
> Sub CustomReDim2(ByRef A(), newU As Long)
>   Dim oldU As Long, emptyVal As TCustomType, i As Long
>   oldU = UBound(A)
>   ReDim Preserve A(newU)
>   For i = oldU + 1 To newU
>     A(i) = emptyVal
>   Next i
> End Sub
> 
> Sub ReDimTest1
>   Dim A(0) As TCustomType, i As Long
>   Const maxIter = 2000
>   For i = 1 To maxIter
>     CustomReDim1(A, i)
>   Next i
> End Sub
> 
> Sub ReDimTest2
>   Dim A(0) As TCustomType, i As Long
>   Const maxIter = 2000
>   For i = 1 To maxIter
>     CustomReDim2(A, i)
>   Next i
> End Sub

Thank you!
