\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 QwtPlotMarker::setLabel(), a label can be assigned to the marker. |
|
The QwtPlotMarker::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 AlignLeft|AlignTop. |
