void KDChart::AbstractLayoutItem::setParentWidget ( QWidget widget  )  [virtual, inherited]

Inform the item about its widget: This enables the item, to trigger that widget's update, whenever the size of the item's contents has changed.

Thus, you need to call setParentWidget on every item, that has a non-fixed size.
