Hi,

Create a context attribute CHART_TYPE of type WDUI_BGTYPE.

And set the type of chart you want by setting this attribute.

lv_chart = '01'.   "Bar type
wd_context->set_attribute
exporting
name = 'CHART_TYPE'
value = lv_chart.

Lekha.

Hi,

Is this the dynamic BG element that is getting generated.

Bind the Chart type of BG to this context attribute. If you want to use it globbaly then create this under a node in the

compoennet controller.

How many views are there. Are you giving any input based on which you are trying to show BG.

You can write it either in WDODINIT or HANDLER for Plugs.

Hi,

On the dropdown selection, set the attribute for chart type.

You have to bind this attribute to the charttype property of the BG.

Hi,

There is no direct binding possible for chart type property of BG. So you need to do that using its handler as follows:

  DATA: lr_view_elem    TYPE REF TO if_wd_view_element,
        lr_bg           TYPE REF TO cl_wd_business_graphics,
        l_chart_type    TYPE WDUI_BGTYPE.

***Changing Customizing file for BG depending on graph
  IF wd_this->gr_view IS NOT INITIAL.                             "Get global view controller from WDDOMODIFY method
***Get Business graphic element from view
    CALL METHOD wd_this->gr_view->get_element
      EXPORTING
        id      = 'BG_TEST'      "Name of Business graph UI element
      RECEIVING
        element = lr_view_elem.
***Get Business graphic element object
    lr_bg ?= lr_view_elem.
l_chart_type = '02'.   "Columns
lr_bg->SET_CHART_TYPE( l_chart_type ).
endif.

Hi,

Sorry, Yes there is no direct binding option available. You can refer to Tesjawin's code for the same.

Hi Arun,

Go to the tab 'Attributes' in your WebDynpro View and define gr_view Type Ref to IF_WD_VIEW. For rest of the procedure follow the steps above.

Also do not forget to assign the view reference to your attributein the WDDOMODIFYVIEW method.

Ie. In the WDDOMODIFYVIEW write:

IF first_time eq abap_true.

wd_this->gr_view = view.

ENDIF.
