I have written a program that uses Win32::OLE to add data to an Excel file and update a chart with the new data. The examples in Using Win32::OLE and Excel were invaluable, but I'm stuck on one last feature. I need to adjust the data ranges in the chart to include the newly-added data. I'm using the following code: 
$sum_sheet->Range("B1:G2")->Copy();
$sum_sheet->ChartObjects(1)->Chart->SeriesCollection->Paste({CategoryL
+abels=>1, NewSeries=>0});

[download]
This correctly adjusts the data range for the chart Values, but the range for the Category (X) Axis Labels is incorrect as follows:
=(Summary!$B$1:$F$1,Summary!$B$1:$G$1)
when it should be:
=(Summary!$B$1:$G$1)
I have also tried using the SeriesCollection->Extend() method, but the results are similar. I've been banging my head on this wall for a while now. Any suggestions?

Thanks in advance,
