.SH "Detailed Description"
.PP 
Attributes of an entry on a legend\&. 

\fBQwtLegendData\fP is an abstract container ( like QAbstractModel ) to exchange attributes, that are only known between to the plot item and the legend\&.
.PP
By overloading \fBQwtPlotItem::legendData()\fP any other set of attributes could be used, that can be handled by a modified ( or completely different ) implementation of a legend\&.
