1、添加属性
2、代码：
method WDDOMODIFYVIEW .
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-BARS
height =
width =
* BIND_TOOLTIP = 'GRAPH.TT'
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.
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.SERIES1'
label = 'Series_1'
view = wd_this->mr_view ).
wd_this->value_cs->ADD_SERIES( lr_bgr_ss ).
lr_bgr_ss = cl_wd_simple_series=>new_simple_series(
bind_value = 'NODE_DYN.SERIES2'
label = 'Series_2'
view = wd_this->mr_view ).
wd_this->value_cs->ADD_SERIES( lr_bgr_ss ).
DATA: lr_bgr_cs TYPE REF TO cl_wd_category.
lr_bgr_cs = cl_wd_category=>new_category(
view = wd_this->mr_view bind_description = 'NODE_DYN.CATEGORY').
wd_this->value_cs->set_category( lr_bgr_cs ).
endmethod.
3、代码：
method INSERT_DATA_CONTEXT .
DATA: lo_node TYPE REF TO if_wd_context_node.
* ls_elem type WD_THIS->element_NODE_DYN,
* lt_elem type WD_THIS->elements_NODE_DYN.
TYPES: BEGIN OF typ_st,
series1 TYPE i,
series2 TYPE i,
category TYPE string,
END OF typ_st.
DATA: ls_elem TYPE typ_st,
lt_elem TYPE TABLE OF typ_st.
ls_elem-series1 = .
ls_elem-series2 = .
ls_elem-category = 'Category 1'.
APPEND ls_elem TO lt_elem.
ls_elem-series1 = .
ls_elem-series2 = .
ls_elem-category = 'Category 2'. APPEND ls_elem TO lt_elem.
ls_elem-series1 = .
ls_elem-series2 = .
ls_elem-category = 'Category 3'.
APPEND ls_elem TO lt_elem.
lo_node = wd_context->get_child_node( name = 'NODE_DYN' ).
lo_node->bind_table( lt_elem ) .
endmethod.
4、代码：
method CREATE_CONTEXT_NODE .
DATA: lo_nodeinfo TYPE REF TO if_wd_context_node_info,
typ_struct type REF TO cl_abap_structdescr,
typ_table TYPE REF TO cl_abap_tabledescr,
com_tab type cl_abap_structdescr=>component_table,
com like LINE OF com_tab.
* component info
com-name = 'SERIES1'.
com-type ?= cl_abap_datadescr=>describe_by_name( 'I' ).
append com to com_tab.
com-name = 'SERIES2'.
com-type ?= cl_abap_datadescr=>describe_by_name( 'I' ).
append com to com_tab.
com-name = 'CATEGORY'.
com-type ?= cl_abap_datadescr=>describe_by_name( 'STRING' ).
append com to com_tab.
* create the structure
typ_struct = cl_abap_structdescr=>create( com_tab ).
* dynamic create the context node
lo_nodeinfo = wd_context->get_node_info( ).
lo_nodeinfo = lo_nodeinfo->add_new_child_node(
name = 'NODE_DYN'
IS_MANDATORY = ABAP_false
IS_MULTIPLE = ABAP_true
STATIC_ELEMENT_RTTI = typ_struct IS_STATIC = ABAP_false ).
endmethod.
5、初始化代码：
method WDDOINIT .
* create one Context Node for Business Graphic
wd_this->create_context_node( ). * node, insert the data to the newly created context node
wd_this->insert_data_context( ).
endmethod.
