Buisness graphics dynamic PIE chart event id

Question

HI all,
I'm trying to create dynamic PIE chart :
Link to sdn document *
First I declared in the context node a table ( 0…n )
PIE – 0…N  with attributes :
Categorty – type string
Series – type i
Then I'm creating the business graphics :
DATA:lr_graph TYPE REF TO cl_wd_business_graphics,
lr_cat TYPE REF TO cl_wd_category,
lr_series TYPE REF TO cl_wd_simple_series,
lr_container TYPE REF TO cl_wd_uielement_container,
lr_flow TYPE REF TO cl_wd_flow_data.
lr_container ?= view->get_element( 'ROOTUIELEMENTCONTAINER' ).
lr_graph = cl_wd_business_graphics=>new_business_graphics(
bind_series_source = 'NODE_DYN'
chart_type = cl_wd_business_graphics=>e_chart_type-pie
height = 340
width = 750
id = 'GRAPH' ).
lr_flow = cl_wd_flow_data=>new_flow_data( element = lr_graph ).
lr_container->add_child( lr_graph ) .
wd_this->value_cs ?= lr_graph.
wd_this->mr_view ?= view.
Now I'm creating the category and series :
wd_this->value_cs =? Lr_graph
wd_this->mr_view ?= view.
Series :
DATA: lr_bgr_ss TYPE REF TO cl_wd_simple_series.
lr_bgr_ss = cl_wd_simple_series=>new_simple_series(
bind_value = ‘NODE_DYN.SERIES’
label = ‘Series_1’
event_id = ‘Series_1’
id       = ‘Series_1’
view = wd_this->mr_view ).
Wd_this->value_cs->add_series( lr_bgr_ss ).
Category :
DATA: lr_bgr_cs TYPE REF TO cl_wd_category.
lr_bgr_cs = cl_wd_category=>new_category(
view = wd_this->mr_view
event_id = ‘Series_1’
id       = ‘Series_1’
bind_description = 'NODE_DYN.CATEGORY').
wd_this->value_cs->set_category( lr_bgr_cs ).
Now I'm binding the data :
Data : ls_pie type wd_this->element_pie.
Data : lt_pie type table of element_pie.
ls_pie-category = 'test_category1'.
ls_pie-series = '34'.
Append ls_pie to lt_pie.
ls_pie-category = 'test_category2'.
ls_pie-series = '73'.
Append ls_pie to lt_pie.
Data : lo_nd_pie type ref to if_Wd_context_node.
Data : lo_el_pie type ref to if_wd_context_element.
Lo_nd_pie = wd_context->get_child_node(
Name = wd_this-> wdctx_pie.
The above is the only way that I succeeded to create 2 categories for the pie chart but I cant isolate the event id for every category.
I tried also to create another series with the same id and other event id but still got the same problem.
Please suggest a solution for creating dynamic pie chart with event id for every category or series .

Arie.

Hi Rama,
Thank you for your reply ,
I added the BIND_EVEND_ID = 'NODE_DYN.SERIES'  and it worked fine.
I'm trying now to get rid of the static context element.
I've declared the following :
DATA : NODE_INFO TYPE REF TO IF_WD_CONTEXT_NODE_INFO ,
              STRUCT_TYPE TYPE REF TO CL_ABAP_STRUCDESCR ,
              TABLE_TYPE REF TO CL_ABAPDESCR=>COMPONENT_TABLE,
             COMP LIKE LINE OF COMP_TAB.
COMP-NAME = 'CATEGORY'.
COMP_TYPE ?= CL_ABAP_DATADESCR=>DESCRIBE_BY_NAME( 'STRING' ).
APPEND COMP TO COMP_TAB.
COMP-NAME = 'SERIES'.
COMP_TYPE ?= CL_ABAP_DATADESCR=>DESCRIBE_BY_NAME( 'I' ).
APPEND COMP TO COMP_TAB.
STRUCT_TYPE = CL_ABAP_STRUCTDESCR=>CREATE( COMP_TAB ).
NODE_INFO = WD_CONTEXT->GET_NODE_INFO( ).
NODE_INFO = NODE_INFO->ADD_NEW_CHILD_NODE (
NAME = 'NODE_DYN'
IS_MANDTORY = ABAP_FALSE
IS_MULTIPLE = ABAP_TRUE
STATIC_ELEMENT_RTTI = STRUCT_TYPE
IS_STATIC = ABAP_FALSE) .
FIELD-SYMBOLS  <TABLE> TYPE TABLE.
FIELD-SYMBOLS  <WA> TYPE WA.
DATA : TABLE TYPE REF TO DATA.
DATA : WA TYPE REF TO DATA.
CREATE DATA TABLE LIKE TABLE OF STRUCT_TYPE.
ASSIGN TABLE->* TO TABLE.
TODO ?? - Add data to FS <TABLE>
*Binding :
DATA : DYN_NODE TYPE REF TO IF_WD_CONTEXT_NODE.
DYN_NODE = WD_CONTEXT->GET_CHILD_NODE( NAME = 'NODE_DYN').
DYN_NODE->BIND_TABLE( <TABLE> ).
How do I append data to FS <table> with the relevant components ?
Is there any  other efficient way to append the data and bind  ?

Arie.
