In 6.x there is a way to add a graph to the Client Home tab for "Client EAP Type Distribution". Yo can access it here: WCS Home > Client Tab > Edit Contents > Tab Name "Client" > Available Components > Add "Client EAP Type Distribution" to the left or right column. This does not seem to exist in 5.2.x though.
In 6.x they added EAP type to the Client Sessions report also. You would need to click customize and add it to the report. Again this is not available in 5.2.x.
