Detailed Description
The QLegendMarker class is an abstract object that can be used to access markers within a legend.
A legend marker consists of an icon and a label. The icon color corresponds to the color used to draw a series and the label displays the name of the series (or the label of the slice for a pie series or bar set for a bar series). A legend marker is always related to one series, slice, or bar set.
See also QLegend.
