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.

This property holds the font of the label.
Access functions:
QFont | font() const |
void | setFont(const QFont &font) |
Notifier signal:
void | fontChanged() |
