\brief 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.
\sa QwtLegend, QwtPlotLegendItem
\note The stockchart example implements a legend as a tree
with checkable items
