Diagramm mit VBA löschen

Sub Makro1()
Range("D5:G6").Select
Charts.Add
ActiveChart.ChartType = xlColumnClustered
ActiveChart.SetSourceData Source:=Sheets("Tabelle1").Range("D5:G6"), PlotBy _
:=xlRows
ActiveChart.Location Where:=xlLocationAsObject, Name:="Tabelle1"
ActiveChart.PlotArea.Select
With Selection.Border
.Weight = xlThin
.LineStyle = xlNone
End With
Selection.Interior.ColorIndex = xlNone
ActiveChart.SeriesCollection(1).Select
With Selection.Border
.Weight = xlThin
.LineStyle = xlNone
End With
Selection.Shadow = False
Selection.InvertIfNegative = False
With Selection.Interior
.ColorIndex = 36
.Pattern = xlSolid
End With
ActiveChart.Axes(xlValue).MajorGridlines.Select
Selection.Delete
ActiveChart.SeriesCollection(1).Select
With Selection.Border
.Weight = xlHairline
.LineStyle = xlNone
End With
Selection.Shadow = False
Selection.InvertIfNegative = False
With Selection.Interior
.ColorIndex = 44
.Pattern = xlSolid
End With
ActiveWindow.Visible = False
Windows("Mappe2").Activate
Range("A1").Select
End Sub

Wie kann ich nun selbiges wieder löschen per Makro? Bzw. wie kann ich das Diagramm anpsrechen bzw. benennen damit ich ein Delete zuweisen kann.
