Many dynamic series in BusinessGraphics

Question

Hi all:
I got a List form RFC. I want to show in a pie chart.
I can't sure the List size.
My idea is dynamic add attribute, and create element.
But it does't work.
my code is like this
List list = wdContext.currentZmtk_Hr_Demo_InputElement().modelObject().getOutput().getIt_Depart();
int a = list.size();
IWDNodeInfo rootNodeInfo = wdContext.getNodeInfo();
IWDNodeInfo categoryNodeInfo = rootNodeInfo.getChild("category");
for (int i = 0; i < list.size(); i++) {
     categoryNodeInfo.addAttribute("seriesValue"+(i+1), "ddic:com.sap.dictionary.double");
     Zmtk_Hr_01 z = (Zmtk_Hr_01) list.get(i);
     String category = z.getDepart();
     short number = z.getNumber();
     ICategoryElement ele = wdContext.createCategoryElement();
     wdContext.nodeCategory().addElement(ele);
     ele.setCategorytext(category);
     ele.setAttributeValue("seriesValue"+(i+1),(double) number+"");
     //ele.setSeriesValue((double) number);
I know this is wrong.
Could anyone show me what to do?

Hi Allen,
1. Have you executed RFC as follows:
wdContext.currentZmtk_Hr_Demo_InputElement().modelObject().execute();
wdContext.nodeOutput().invalidate();
Because only after execute you will get output in to your modal node.
2. I have not worked in dynamic programming much but i believe that code
categoryNodeInfo.addAttribute("seriesValue", "ddic:com.sap.dictionary.double");
must be before for loop. And for setting data into this attribute inside for loop code will be
ele.setAttributeValue("seriesValue",(double) number+"");
