Wrapping output to a new line
To specify how many graphs should be displayed on one line before the output wraps to another line, add statements similar to these (this step is necessary only for pie charts):
'Set the number of pie columns before wrapping to
'the next line
obj.PieColumns = nCols
obj.SetTitle "Charting Sample For " & nSite & " Sites"
For i=0 To nSite-1
