Yes, but not how you have done it
To make a range dynamic you must use a Named Range,
Typically like
MyRange: =offset(B1,A1,0,A2,1)
where A1 is the Start Row offset from A1 and A2 is the length of the range
and then use the named range in the Chart Series
=Series(,,MyRange,1)
For more info have a read of : http://chandoo.org/wp/2009/10/15/dynamic-chart-data-series/
Beware that you can't use the word "chart" as a named range or part of a range in a Chart in Excel 2007.
