Hi Suman

one category is getting displayed but not all because it takes the last category and provide the output

Look

The Category describes the categories of a graphical representation. Categories of a chart are a discrete value range or an unsorted set of objects - such as January, February, March, and so on

So if u want data for each category so u have pass it one by one because It seems to me that RFC is designed in this way ? It doesn't take ArayList of Category.

So for each Category you have to call rfc .

understand from this example

IPrivateGenCompView.IRegionElement resEle = wdContext.createAndAddRegionElement();
		resEle.setRegionName("India");
		{
			// India has this many location each will respresented as category
			// in Business graph and to retrieve each category u have to call your rfc
			IPrivateGenCompView.ILocationElement location_ele1 = resEle.nodeLocation().createAndAddLocationElement();
			location_ele1.setLocationName("Mumbai");

			IPrivateGenCompView.ILocationElement location_ele2 = resEle.nodeLocation().createAndAddLocationElement();
			location_ele2.setLocationName("Delhi");

			IPrivateGenCompView.ILocationElement location_ele3 = resEle.nodeLocation().createAndAddLocationElement();
			location_ele3.setLocationName("Calcutta");
		}
