Cl_chart_engine is not refreshing with new value.

[Former Member]

HI All ,

            I am passing the value of internal table for the first time it is updating the correct graph , but after pressing the back button i am passing new value to the internal table and but  graph is not refreshing .

             LOOP AT gt_chart INTO gwa_chart.

             lobj_element = xu_ixml_doc->create_simple_element(

             name = 'C' parent = lobj_categories ).

            lobj_element->if_ixml_node~set_value( gwa_chart-text ).

            lobj_element = xu_ixml_doc->create_simple_element(

           name = 'S' parent = lobj_series ).

           lobj_element->if_ixml_node~set_value( gwa_chart-value ).

           endloop.

You must be calling methods set_data and render of class instance cl_gui_chart_engine in PBO module.

Put a breakpoint and check whether on repeat attempt, fresh data is being set or not.

Hi Manish,

I have also similar requirement and i use set method and render the class instance . The data is Passing Perfectly but second time data is passing correctly but it is not updating with new value.

     gobj_ce_viewer->set_data( xdata = lv_xstr ).

     lobj_ostream = gobj_ixml_sf->create_ostream_xstring( lv_xstr ).

     CALL METHOD lobj_ixml_custom_doc->render

       EXPORTING

         ostream = lobj_ostream.

     gobj_ce_viewer->set_customizing( xdata = lv_xstr ).

Thanks

It is possible that in PBO module, you have put code that runs only when custom container in INITIAL.

Because of such validation, internal table gets assigned to chart only on first PBO run.

On subsequent PBO runs, even if internal table changes, the changes won't get registered in chart because custom container is no longer initial.

Hi Manish ,

Thanks for the reply .

For that reason i free the custom custom container each time and value is passing correctly.but chart value is not populated on the screen.

Thanks

and ,

I was able to do it by calling method free of class cl_gui_custom_container.

Put below statement in PAI module and see what happens.

 go_container->free( ).

Hi Manish,

Thanks for your reply.

I have already free the container in PAI module .

When 'BACK'

IF gobj_ce_container IS NOT INITIAL.

         gobj_ce_container->free( ).

       ENDIF.

LEAVE TO SCREEN 0.

One more question here if we are using module pool to generate selection screen and one more screen to display the chart then it will work or not because if we are checking standard program

they didn't use module pool program to generate  selection screen .

Thanks

It should work.

This theory can be confirmed by copying the standard program and modifying it.
