\brief A class for drawing markers
A marker can be a horizontal line, a vertical line,
a symbol, a label or any combination of them, which can
be drawn around a center point inside a bounding rectangle.
The QwtPlotMarker::setSymbol() member assigns a symbol to the marker.
The symbol is drawn at the specified point.
With setLabel(), a label can be assigned to the marker.
The setLabelAlignment() member specifies where the label is
drawn. All the Align*-constants in Qt::AlignmentFlags (see Qt documentation)
are valid. The interpretation of the alignment depends on the marker's
line style. The alignment refers to the center point of
the marker, which means, for example, that the label would be printed
left above the center point if the alignment was set to
Qt::AlignLeft | Qt::AlignTop.
