Most items are represented by one entry on the legend

QwtLegendData is basically a list of QVariants that makes it
possible to overload and reimplement legendData() to
return almost any type of information, that is understood
by the receiver that acts as the legend.
The default implementation returns one entry with
the title() of the item and the legendIcon().
