Help with OLE Series

Hello,

I am using ORACLE OLE2 package to print a series bar graph in excel. I need
to rename "Series Name" that comes out in as a char in excel. By defual the
series are names as Series1, Series2, Series3,.....SeriesN. How can I access
the handle to "Series Name" which help me change its name. Any help will be
highly appreciated.

Thanks you,
Bilal
