parameter will be pieSectionFormat and allows a string with specific substitution values for section key (name), value, and percent value. Use %0% %1% %2% for these values respectively. Note that the underlying jfreechart API has changed the default for how this is display between version 1.0.0 and 1.0.3, so this parameter is necessary in order to give user the ability to get a compatible look. While it was possible to maintain existing look, it has been decided to go to the new default behavior (no values shown) as it is cleaner looking and consistent with jFreechart default. Users needing the old behavior can add the pieSectionFormat = %0% = %1%. This capability is only available if jfreechart 1.0.3 or higher is installed in ..../WEB-INF/lib !!!!
