ADF DVT PieGraph Drilling Option

Question

Hi
JDev Version : 11.1.2.0.0
UseCase : Need to implement adf pie graph with drill up and drill down options (as in BI Reporting). Data aligns with this options REGION - COUNTRY - STATE and so on.
Goal : On the same view, at any point of time only one pie graph needs to be displayed. For example, by default a REGION pie graph is displayed. On click of a REGION (say NAM or CAM or ..) same pie graph needs to drilled down to COUNTRY level pie graph and so on so forth.
I could not find much on this drilling behavior for pie graph. Could you please point me to some demos if available.
P.S: I already implemented the same without drilling behavior but using multiple views, meaning different pie graphs for different layers ( REGION, COUNTRY.....)
Please let me know if you need more information if am unclear.
Thanks and Appreciate your response.

Hey Balu,
Glad you could do it. Maybe you could also show me your code, in here or even by email.
Here's my code and remember it all comes from the same dataControl, in this case, a fact table.
(I won't put the barGraph code since it is the code made by the wizard with the option drillingEnabled = true)
PageDefinition File code:
<graph IterBinding="VFactSalesNewView1Iterator" id="VFactSalesNewView1" xmlns="http://xmlns.oracle.com/adfm/dvt"
               type="BAR_VERT_CLUST">
            <graphDataMap convert="false" leafOnly="true">
                <hierarchies>
                    <item value="FkStore">
                        <child value="IdAno"/>
                    </item>
                </hierarchies>
                <drills type="REPLACE"/>
                <series>
                    <data aggregateDuplicates="true" defaultAggregateType="SUM">
                        <item value="Amount" aggregateType="SUM"/>
                    </data>
                </series>
                <groups>
                    <item value="FkStore"/>
                </groups>
            </graphDataMap>
        </graph>
Ps - i could only make a level 1 drill
In my case: all stores (1 through 29), you click one and it will show the amount of sales divided by year. Stores sales (total) -> selected store sales by years.
Regards and hope it helps,
