#include <KDChartLegend.h>
Inheritance diagram for KDChart::Legend:
Legend is the class for drawing legends for all kinds of diagrams ("chart types").
Legend is drawn on chart level, not per diagram, but you can have more than one legend per chart, using KDChart::Chart::addLegend().

void Legend::setFloatingPosition | ( | const RelativePosition & | relativePosition | ) |
Specify the position and alignment of a floating legend.

To have the legend positioned at a fixed point, measured from the QPainter's top left corner, you could use the following code code:
KDChart::RelativePosition relativePosition; relativePosition.setReferencePoints( PositionPoints( QPointF( 0.0, 0.0 ) ) ); relativePosition.setReferencePosition( Position::NorthWest ); relativePosition.setAlignment( Qt::AlignTop | Qt::AlignLeft ); relativePosition.setHorizontalPadding( KDChart::Measure( 4.0, KDChartEnums::MeasureCalculationModeAbsolute ) ); relativePosition.setVerticalPadding( KDChart::Measure( 4.0, KDChartEnums::MeasureCalculationModeAbsolute ) ); m_legend->setFloatingPosition( relativePosition );
