difference in DataSource?

Post by Jackie_chai » Wed Sep 19, 2001 6:38 am

Hello,everyone

who can tell me the difference between DefaultCategoryDataSource and DefaultXYDataSource in JFreeChart?
what kinds of chart they are used in separately?
if i only make use of VBar/HBar/Line/Pie chart, can i ignore the DefaultXYDataSource?

thanx
