Got Solution after Many Effort:
I use same datasource for Chart and Table
and Create collection parameter for jav collection with same name of java colection which derived in parameter by java code
in first where i user datasource firsttime i user datasource expression as "$P{collectionParameter}.Clonable()"
and For Chart  i use Dataset Expression as "$P{collectionParameter}".
and i get Chart and table both using same dataSet and same DataSource..
