DVT X Axis Date Formatting using tabular data

Question

Hi,
I have a curious question about the <dvt:attributeFormat>.
I wanted to format my bar graph x-axis with locale sensitive date formatting.
I saw this attribute <dvt:attributeFormat> which I think is the best tool for the job.
<dvt:barGraph id="wsssudg1" subType="BAR_VERT_CLUST" tabularData="#{myBean.tabularData}">
          <dvt:a t t r i b u t e F o r m a t  >
               <af:convertDateTime locale="#{myBean.locale}"/>
          </dvt:a t t r i b u t e F o r m a t  >       
</dvt:barGraph>
My only concern is this.  I am not using page binding in building my graph data but using tabularData property instead.
I am passing a java.util.Date object also from my getTabularData method
public class MyBean{
    public List getTabularData(){
        /*More code her*/
        return list;
According to the java docs here http://docs.oracle.com/cd/E24382_01/apirefs.1112/e17490/tagdoc/dvt_attributeFormat.html
The name of the categorical attribute is the name of the attribute/layer that was added to the Graph DataModel. The Graph model can be set declaratively by updating the pagedef. Here is the associated view pagedef for the above graph:
<graph IterBinding="EmpView1Iterator" id="EmpView1"
      xmlns="http://xmlns.oracle.com/adfm/dvt" type="BAR_VERT_CLUST">
    <graphDataMap leafOnly="true">
        <series>
          <data>
            <item value="Bonus"/>
          </data>
        </series>
        <groups>
          <item value="Hiredate"/>
        </groups>
    </graphDataMap>
</graph
>
..but since I am not using page binding then what name should I put there?
Any DVT experts around?

Answer 1

I tried different name but I cant find the correct attribute name.  Tried 'object', 'attribute 1' etc but it seems not correct.
<dvt:barGraph id="wsssudg1" subType="BAR_VERT_CLUST" tabularData="#{myBean.tabularData}">
          <dvt:a t t r i b u t e F o r m a t  >
               <af:convertDateTime locale="#{myBean.locale}"/>
          </dvt:a t t r i b u t e F o r m a t  >       
</dvt:barGraph>
Does this mean that this tag only works when you are using page binding?
If you are using tabulardata in managing your data then does it mean that you cannot use this tag?
Then how do you format DVT graph data that uses tabularData if you do not know the attribute name?
The javadoc tag reference does not mention anything about this.
Anyone has experience in dealing with this scenario?
Use case:
How do you format date attribute in a locale sensitive manner when your graph is using custom list in the tabulardata tag property of your graph component.
Thanks
