Pie graph slice derivation returning two rows

Question

Hi All,
I have a requirement to derive the series name when the user clicks on a pie graph's series.
Below is my pie graphs code
<dvt:pieGraph id="pieGraph1"
value="#{bindings.DashboardTransPieVO1.graphModel}"
subType="PIE" threeDEffect="true"
animationOnDisplay="auto"
seriesRolloverBehavior="RB_HIGHLIGHT"
dynamicResize="DYNAMIC_SIZE" style="Default"
partialTriggers="::cil2"
clickListener="#{viewScope.DashboardScreenBean.drillPie}"
drillingEnabled="true">
<dvt:background>
<dvt:specialEffects/>
</dvt:background>
<dvt:graphPieFrame/>
<dvt:seriesSet>
<dvt:series/>
</dvt:seriesSet>
<dvt:legendTitle text="#{ethuiBundle.TRANSACTION_STATES}"
rendered="true"/>
<dvt:graphFootnote text="Footnote" rendered="false"/>
<dvt:sliceLabel>
<dvt:numberFormat numberType="NUMTYPE_GENERAL"
decimalDigit="0"/>
</dvt:sliceLabel>
<dvt:pieLabel rendered="false"/>
<dvt:graphSubtitle text="Subtitle" rendered="false"/>
<dvt:graphTitle text="Title" rendered="false"/>
</dvt:pieGraph>
I am using following code for that in clickListener of pie graph:
ComponentHandle handle = clickEvent.getComponentHandle();
if (handle instanceof DataComponentHandle)
DataComponentHandle dhandle = (DataComponentHandle)handle;
// Get the value displayed in the series
System.out.println(" @@@@Value: " + dhandle.getValue(DataComponentHandle.UNFORMATTED_VALUE));
// Get the series attributes
Attributes [] seriesInfo = dhandle.getSeriesAttributes();
if(seriesInfo != null)
for(Attributes attrs: seriesInfo)
System.out.println(" @@@@Series value: " + attrs.getValue(Attributes.LABEL_VALUE));
System.out.println(" @@@@Series name: " + attrs.getValue(Attributes.LABEL_ATTRIBUTE));
System.out.println(" @@@@Series value id: " + attrs.getValue(Attributes.ID_VALUE));
System.out.println(" @@@@Series name id: " + attrs.getValue(Attributes.ID_ATTRIBUTE));
The issue is it is returning me two rows for Attributes array. The first row is containing nulls in Attributes array with the exception of ID value and ID Attribute. They carry some standard value like 0 and some text respectively for them.
The 2nd row contains the data I am looking for.
My query is why two rows are being returned?
Thanks

Check this code:
REPORT  ytest_pie.
DATA: BEGIN OF data  OCCURS 1,
        text(36),
        feld1 TYPE p,
      END OF data,
      BEGIN OF opts OCCURS 1,
        c(80) TYPE c,
      END OF opts,
      BEGIN OF tyear OCCURS 1,
        c(20) TYPE c,
      END OF   tyear.
opts-c = 'P2TYPE = PI'.
APPEND opts.
data-text = 'X 10'.
data-feld1 = '10'.
APPEND data.
data-text = 'Y 20'.
data-feld1 = '20'.
APPEND data.
CALL FUNCTION 'GRAPH_MATRIX_2D'
  TABLES
    data        = data
    opts        = opts
    tcol        = tyear
  EXCEPTIONS
    col_invalid = 1
    opt_invalid = 2
    OTHERS      = 3.
IF sy-subrc <> 0.
MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
        WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
ENDIF.
