Hi,

If you turn your data cells into a List, or Table in xl2007, the chart will
auto expand.

The named range approach will work if you set up the names correctly.
See here for more information.

I have A Chart Defined by Category (X) values in Collumn B and Y values in
Collumn C. Right now Both are defined by rows 4 to 114.
I would like to be able to have the chart automatically redefine itself so
if I put a value in C115 the chart would automaticaly set Y value range to
be
C4:C115 eithout having to manually define chart. Is this possible? If so
how? I've tried OFFSET bu so far no luck.
