The sizeHint of legend and axis widgets depend on the text that is displayed 
on them. The layout of the plot widget depends on these sizeHints and should 
be adjusted, whenever you change the texts. So simply assign a new title and 
the layout should be recalculated.

In detail: the layout is updated with QwtPlot::updateLayout, but you should 
not have to call it manually, because QwtPlot handles LayoutRequest events 
from its children.
