A WPaintedWidget in a WScrollArea (or WContainerWidget with CSS overflow
configured) should behave as expected: resize the widget to the greater
virtual size. Perhaps you expect to only be able to draw the diagram
partially (and receive a partial paint event) for the visible area? That is
not foreseen, but could be implemented by reacting to scroll events to
update the diagram.

You need to size the chart to its virtual size.
