Detailed Description

The class for cartesian axes.

For being useful, axes need to be assigned to a diagram, see AbstractCartesianDiagram::addAxis and AbstractCartesianDiagram::takeAxis.

PolarAxis, AbstractCartesianDiagram

Definition at line 39 of file KChartCartesianAxis.h.

Constructor & Destructor Documentation

CartesianAxis::CartesianAxis ( AbstractCartesianDiagram diagram = nullptr)
explicit

C'tor of the class for cartesian axes.

Note
If you pass a null parent to the constructor, you need to call your diagram's addAxis function to add your axis to the diagram. Otherwise there is no need to call addAxis, since the constructor does it already.

AbstractCartesianDiagram::addAxis

Member Function Documentation

QMap< qreal, QString > CartesianAxis::annotations ( ) const

Returns the currently set axis annotations.

Definition at line 1132 of file KChartCartesianAxis.cpp.

bool CartesianAxis::compare ( const CartesianAxis other) const

Returns true if both axes have the same settings.

Definition at line 412 of file KChartCartesianAxis.cpp.

Returns the length of custom ticks on the axis.

Definition at line 1121 of file KChartCartesianAxis.cpp.

QList< qreal > CartesianAxis::customTicks ( ) const

Returns the currently set custom ticks on the axis.

Definition at line 1147 of file KChartCartesianAxis.cpp.

overridevirtual

reimpl

Implements KChart::AbstractLayoutItem.

Definition at line 543 of file KChartCartesianAxis.cpp.

void CartesianAxis::paintCtx ( PaintContext context)
overridevirtual

reimpl

Reimplemented from KChart::AbstractLayoutItem.

Reimplemented in KChart::LeveyJenningsAxis.

Definition at line 658 of file KChartCartesianAxis.cpp.

void CartesianAxis::resetTitleTextAttributes ( )

Reset the title text attributes to the built-in default:

Same font and pen as AbstractAxis::textAttributes() and 1.5 times their size.

Definition at line 462 of file KChartCartesianAxis.cpp.

void CartesianAxis::setAnnotations ( const QMap< qreal, QString > &  annotations)

Sets the axis annotations to annotations.

Annotations are a QMap of qreals and QStrings defining special markers and their position. If you use annotations, the normal ticks and values will be invisible. To unset the annotations, pass an empty QMap.

Definition at line 1137 of file KChartCartesianAxis.cpp.

void CartesianAxis::setCustomTickLength ( int  value)

Sets the length of custom ticks on the axis.

Definition at line 1111 of file KChartCartesianAxis.cpp.

void CartesianAxis::setCustomTicks ( const QList< qreal > &  ticksPostions)

Sets custom ticks on the axis.

Ticks are a QList of qreals defining their special position.

Definition at line 1152 of file KChartCartesianAxis.cpp.

void CartesianAxis::setGeometry ( const QRect r)
overridevirtual

pure virtual in QLayoutItem

Implements KChart::AbstractAxis.

Definition at line 1097 of file KChartCartesianAxis.cpp.

void CartesianAxis::setTitleSize ( qreal  value)

use setTitleTextAttributes() instead

Deprecated:

Definition at line 602 of file KChartCartesianAxis.cpp.

void CartesianAxis::setTitleSpace ( qreal  value)
Deprecated:
Sets the spacing between the title and the diagram.

Be aware that setting this value can lead to collisions between axis labels and the title

Definition at line 592 of file KChartCartesianAxis.cpp.

void CartesianAxis::setTitleText ( const QString text)

Sets the optional text displayed as chart title.

Definition at line 430 of file KChartCartesianAxis.cpp.

QSize CartesianAxis::sizeHint ( void  ) const
overridevirtual

pure virtual in QLayoutItem

Implements QLayoutItem.

Definition at line 1091 of file KChartCartesianAxis.cpp.

qreal CartesianAxis::titleSize ( ) const
Deprecated:

Definition at line 608 of file KChartCartesianAxis.cpp.

qreal CartesianAxis::titleSpace ( ) const
Deprecated:

Definition at line 597 of file KChartCartesianAxis.cpp.

TextAttributes CartesianAxis::titleTextAttributes ( ) const

Returns the text attributes that will be used for displaying the title text.

This is either the text attributes as specified by setTitleTextAttributes, or (if setTitleTextAttributes() was not called) the default text attributes.
