Hi experts,

I copy the code of program GRAPHICS_GUI_CE_DEMO to create a dynamic graph.

I create two list box on screen and a container, I split container in two part 1 for alv and second for graph.

if user change the list box field, alv will change and graph also will change.

i use below code in pbo of screen. it work but when user change list box, alv contains are change but graph

area display only chart grids only, no columns and other things like title etc. are displaying.

if i comment CALL METHOD l_ixml_custom_doc->render at end, the graph display changes but

customize setting not apply.
