Attributes of an entry on a legend.
QwtLegendData is an abstract container ( like QAbstractModel ) to exchange attributes, that are only known between to the plot item and the legend.
By overloading QwtPlotItem::legendData() any other set of attributes could be used, that can be handled by a modified ( or completely different ) implementation of a legend.
