When I am building a line chart to display accounting data, the data often
consists of historical and projected numbers. Say I had historical data for
January-December 2008 and projected data for January - December 2009 and
wanted to show all 24 months on the same line in a chart with the 2008 part
of the line in green and the 2009 part blue, how would I do that?

Thanks in advance
Bill
