macro loop through 2 worksheets

[asdzxc]

After applying macro on Sheet1,go to Sheet2 and to apply the same macro but starting from 'Set cht1 = ActiveSheet.Shapes.AddChart'
plse add code
Dim lastrow As Long
Dim selectnum As Long
lastrow = Cells(Rows.Count, "a").End(xlUp).Row
Select Case True
Case lastrow > 30: selectnum = 30
Case lastrow > 20: selectnum = 20
Case lastrow > 10: selectnum = lastrow
End Select
Cells(lastrow - selectnum + 1, "a").Resize(selectnum, 3).Select
Set cht1 = ActiveSheet.Shapes.AddChart
cht1.Chart.ChartType = xlLineMarkers
cht1.Chart.Location xlLocationAsNewSheet
ActiveChart.ChartArea.Select
ActiveChart.PlotArea.Select
, plse add code
