Detailed Description

Legend defines the interface for the legend drawing class.

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 KChart::Chart::addLegend().

Note
Legend is different from all other classes ofd KChart, since it can be displayed outside of the Chart's area. If you want to, you can embedd the legend into your own widget, or into another part of a bigger layout, into which you might have inserted the Chart.

On the other hand, please note that you MUST call Chart::addLegend to get your legend positioned into the correct place of your chart - if you want to have the legend shown inside of the chart (that's probably true for most cases).

void Legend::paint ( QPainter painter)
overridevirtual

Overwrite this to paint the inner contents of your widget.

Note
When overriding this method, please let your widget draw itself at the top/left corner of the painter. You should call rect() (or width(), height(), resp.) to find the drawable area's size: While the paint() method is being executed the frame of the widget is outside of its rect(), so you can use all of rect() for your custom drawing!

void Legend::replaceDiagram ( KChart::AbstractDiagram newDiagram,
KChart::AbstractDiagram oldDiagram = nullptr 
)

Replaces the old diagram, or appends the new diagram, it there is none yet.

Parameters
newDiagramThe diagram to be used instead of the old one. If this parameter is zero, the first diagram will just be removed.
oldDiagramThe diagram to be removed by the new one. This diagram will be deleted automatically. If the parameter is omitted, the very first diagram will be replaced. In case, there was no diagram yet, the new diagram will just be added.

void Legend::resetTexts ( )

Removes all legend texts that might have been set by setText.

This resets the Legend to default behaviour: Texts are created automatically.

Definition at line 595 of file KChartLegend.cpp.

void Legend::setAlignment ( Qt::Alignment  alignment)

Specify the alignment of a non-floating legend.

Use setFloatingPosition to set position and alignment if your legend is floating.

alignment, setPosition, setFloatingPosition

Definition at line 482 of file KChartLegend.cpp.

void Legend::setColor ( uint  dataset,
const QColor color 
)

Note: there is no color() getter method, since setColor just sets a QBrush with the respective color, so the brush() getter method is sufficient.

Definition at line 627 of file KChartLegend.cpp.

void Legend::setDiagram ( KChart::AbstractDiagram newDiagram)

A convenience method doing the same as replaceDiagram( newDiagram, 0 );.

Replaces the first diagram by the given diagram. If the legend's list of diagram is empty the given diagram is added to the list.

void Legend::setFloatingPosition ( const RelativePosition relativePosition)

Specify the position and alignment of a floating legend.

Use setPosition and setAlignment to set position and alignment if your legend is non-floating.

Note
When setFloatingPosition is called, the Legend's position value is set to KChart::Position::Floating automatically.

If your Chart is pointed to by m_chart, your could have the floating legend aligned exactly to the chart's coordinate plane's top-right corner with the following commands:

KChart::RelativePosition relativePosition;
relativePosition.setReferenceArea( m_chart->coordinatePlane() );
relativePosition.setReferencePosition( Position::NorthEast );
relativePosition.setAlignment( Qt::AlignTop | Qt::AlignRight );
relativePosition.setHorizontalPadding(
    KChart::Measure( -1.0, KChartEnums::MeasureCalculationModeAbsolute ) );
relativePosition.setVerticalPadding(
    KChart::Measure( 0.0, KChartEnums::MeasureCalculationModeAbsolute ) );
m_legend->setFloatingPosition( relativePosition );
   To have the legend positioned at a fixed point, measured from the QPainter's top left corner,
   you could use the following code code:
KChart::RelativePosition relativePosition;
relativePosition.setReferencePoints( PositionPoints( QPointF( 0.0, 0.0 ) ) );
relativePosition.setReferencePosition( Position::NorthWest );
relativePosition.setAlignment( Qt::AlignTop | Qt::AlignLeft );
relativePosition.setHorizontalPadding(
    KChart::Measure( 4.0, KChartEnums::MeasureCalculationModeAbsolute ) );
relativePosition.setVerticalPadding(
    KChart::Measure( 4.0, KChartEnums::MeasureCalculationModeAbsolute ) );
m_legend->setFloatingPosition( relativePosition );

Actually that's exactly the code KChart is using as default position for any floating legends, so if you just say setPosition( KChart::Position::Floating ) without calling setFloatingPosition your legend will be positioned at point 4/4.

void Legend::setHiddenDatasets ( const QList< uint >  hiddenDatasets)

Sets a list of datasets that are to be hidden in the legend.

By passing an empty list, you show all datasets. All datasets are shown by default, which means that hiddenDatasets() returns an empty list.

Definition at line 1254 of file KChartLegend.cpp.

void Legend::setLegendSymbolAlignment ( Qt::Alignment  alignment)

Specify the alignment of the legend symbol( alignment of Legend::LinesOnly) within the legend.

See also
legendSymbolAlignment()

Definition at line 510 of file KChartLegend.cpp.

void Legend::setMarkerAttributes ( uint  dataset,
const MarkerAttributes markerAttributes 
)

Note that any sizes specified via setMarkerAttributes are ignored, unless you disable the automatic size calculation, by saying setUseAutomaticMarkerSize( false )

Definition at line 702 of file KChartLegend.cpp.

void Legend::setPosition ( Position  position)

Specify the position of a non-floating legend.

Use setFloatingPosition to set position and alignment if your legend is floating.

See also
setAlignment, setFloatingPosition

Definition at line 461 of file KChartLegend.cpp.

void Legend::setReferenceArea ( const QWidget area)

Specifies the reference area for font size of title text, and for font size of the item texts, IF automatic area detection is set.

Note
This parameter is ignored, if the Measure given for setTitleTextAttributes (or setTextAttributes, resp.) is not specifying automatic area detection.

If no reference area is specified, but automatic area detection is set, then the size of the legend's parent widget will be used.

See also
KChart::Measure, KChartEnums::MeasureCalculationMode

Definition at line 295 of file KChartLegend.cpp.

void Legend::setTextAlignment ( Qt::Alignment  alignment)

Specify the alignment of the text elements within the legend.

See also
textAlignment()

Definition at line 496 of file KChartLegend.cpp.

void Legend::setUseAutomaticMarkerSize ( bool  useAutomaticMarkerSize)

This option is on by default, it means that Marker sizes in the Legend will be the same as the font height used for their respective label texts.

Set this to false, if you want to specify the marker sizes via setMarkerAttributes or if you want the Legend to use the same marker sizes as they are used in the Diagrams.

Definition at line 583 of file KChartLegend.cpp.

Qt::Alignment Legend::textAlignment ( ) const

Returns the alignment used while rendering text elements within the legend.
