Hi Pavan,
Under the Business Graph UI add the Category as usual, add a single Series. Under the Series add a Point and for the Point add a Value of type NumericValue.
Create a Node for Category Say Vn_Category and an Attribute Under it say Va_CategoryName and bind Description property of Category to Vn_Category-->Va_CategoryName .
Create another node structure as shown below for Series,
Vn_Series
    --Vn_Point(Child Node)
Va_Value(Type Int)
Va_PointIndex(Type String)
Va_ToolTip(Type String)
Set the Singleton property of Vn_Point node as false.
The PointSource property of Series to be bound to Vn_Series-->Vn_Point.
The ValueSource property of Point to be bound to Vn_Series>Vn_Point, Tooltip to Vn_Series>Vn_Point>Va_ToolTip and eventid property to Vn_Series>Vn_Point-->Va_PointIndex.
The Value property of NumericValue to Vn_Series>Vn_Point>Va_Value, and make sure Type is defined as "Y".
Create so many series(parent node) elements as many series you need in the graph and using each series(parent node) element create so many point(Child node) elements as many bars or as many categories are there in the graph.
Example:
//Creating 4 Series
IPrivateKpiChartView.IVn_SeriesElement elSeriesElement1 = null;
IPrivateKpiChartView.IVn_SeriesElement elSeriesElement2 = null;
IPrivateKpiChartView.IVn_SeriesElement elSeriesElement3 = null;
IPrivateKpiChartView.IVn_SeriesElement elSeriesElement4 = null;
elSeriesElement1 = wdContext.nodeVn_Series().createAndAddVn_SeriesElement();
elSeriesElement2 = wdContext.nodeVn_Series().createAndAddVn_SeriesElement();
elSeriesElement3 = wdContext.nodeVn_Series().createAndAddVn_SeriesElement();
elSeriesElement4 = wdContext.nodeVn_Series().createAndAddVn_SeriesElement();
//Populating 5 Categories and corresponding values,
IPrivateKpiChartView.IVn_CategoryElement elCategoryElement = null;
IPrivateKpiChartView.IVn_PointElement elPointElement1 = null;
IPrivateKpiChartView.IVn_PointElement elPointElement2 = null;
IPrivateKpiChartView.IVn_PointElement elPointElement3 = null;
IPrivateKpiChartView.IVn_PointElement elPointElement4 = null;
for (int index = 0; index < 5; index++) {
elCategoryElement = wdContext.nodeVn_Category().createAndAddVn_CategoryElement();
elCategoryElement.setVa_CategoryName("Category"+index);
elPointElement1 = elSeriesElement1.nodeVn_Point().createAndAddVn_PointElement();
elPointElement1.setVa_PointIndex("0s"+index);
elPointElement1.setVa_Value(index+1); //The value to be displayed on the graph.
elPointElement1.setVa_ToolTip("Series 1");
elPointElement2 = elSeriesElement2.nodeVn_Point().createAndAddVn_PointElement();
elPointElement2.setVa_PointIndex("1s"+index);
elPointElement1.setVa_Value(index+2);
elPointElement2.setVa_ToolTip("Series 2");
elPointElement3 = elSeriesElement3.nodeVn_Point().createAndAddVn_PointElement();
elPointElement3.setVa_PointIndex("2s"+index);
elPointElement1.setVa_Value(index+3);
elPointElement3.setVa_ToolTip("Series 3");
elPointElement4 = elSeriesElement4.nodeVn_Point().createAndAddVn_PointElement();
elPointElement4.setVa_PointIndex("3s"+index);
elPointElement1.setVa_Value(index+4);
elPointElement4.setVa_ToolTip("Series 4");
Using the snippet in my previous replay, u can extract the selected series point's value and the corresponding category.
Also you can refer the wiki link [WIKI|http://wiki.sdn.sap.com/wiki/display/WDJava/WebDynproDynamicBusiness+Graphics]
