Detailed Description

The base class for axes.

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

PolarAxis, AbstractCartesianDiagram

Definition at line 54 of file KChartAbstractAxis.h.

Member Function Documentation

bool AbstractAxis::compare ( const AbstractAxis other) const

Returns true if both axes have the same settings.

Definition at line 142 of file KChartAbstractAxis.cpp.

void AbstractAxis::connectSignals ( )
virtual

Wireing the signal/slot connections.

This method gets called automatically, each time, when you assign the axis to a diagram, either by passing a diagram* to the c'tor, or by calling the diagram's setAxis method, resp.

If overwriting this method in derived classes, make sure to call this base method AbstractAxis::connectSignals(), so your axis gets connected to the diagram's built-in signals.

See also
AbstractCartesianDiagram::addAxis()

Definition at line 174 of file KChartAbstractAxis.cpp.

const AbstractCoordinatePlane * AbstractAxis::coordinatePlane ( ) const

Convenience function, returns the coordinate plane, in which this axis is used.

If the axis is not used in a coordinate plane, the return value is Zero.

Definition at line 238 of file KChartAbstractAxis.cpp.

void AbstractAxis::createObserver ( AbstractDiagram diagram)

Method invoked by AbstractCartesianDiagram::addAxis().

You should not call this function, unless you know exactly, what you are doing.

See also
connectSignals(), AbstractCartesianDiagram::addAxis()

Definition at line 164 of file KChartAbstractAxis.cpp.

const QString AbstractAxis::customizedLabel ( const QString label) const
virtual

Reimplement this method if you want to adjust axis labels before they are printed.

KChart is calling this method immediately before drawing the text, this means: What you return here will be drawn without further modifications.

Parameters
labelThe text of the label as KChart has calculated it automatically (or as it was taken from a QStringList provided by you, resp.)
Note
If you reimplement this method in a subclass of KChart::CartesianAxis, and your reimplementation's return value depends on data other than label (so KChart will not know when it changes), you must manually ensure that layouts are adapted to any changed sizes of the axis labels. To do that, call KChart::CartesianAxis::layoutPlanes() from your reimplementation when you know that the external data changed and it will change label sizes - or when you cannot exclude that.
Returns
The text to be drawn. By default this is the same as label.

Definition at line 158 of file KChartAbstractAxis.cpp.

void AbstractAxis::delayedInit ( )
protectedvirtualslot

called for initializing after the c'tor has completed

Definition at line 134 of file KChartAbstractAxis.cpp.

void AbstractAxis::deleteObserver ( AbstractDiagram diagram)

Method invoked by AbstractCartesianDiagram::takeAxis().

You should not call this function, unless you know exactly, what you are doing.

See also
AbstractCartesianDiagram::takeAxis()

Definition at line 169 of file KChartAbstractAxis.cpp.

QStringList AbstractAxis::labels ( ) const

Returns a list of strings, that are used as axis labels, as set via setLabels.

See also
setLabels

Definition at line 219 of file KChartAbstractAxis.cpp.

RulerAttributes AbstractAxis::rulerAttributes ( ) const

Returns the attributes to be used for painting the rulers.

See also
setRulerAttributes

Definition at line 205 of file KChartAbstractAxis.cpp.

void AbstractAxis::setLabels ( const QStringList list)

Use this to specify your own set of strings, to be used as axis labels.

Labels specified via setLabels take precedence: If a non-empty list is passed, KChart will use these strings as axis labels, instead of calculating them.

If you pass a smaller number of strings than the number of labels drawn at this axis, KChart will repeat the strings until all labels are drawn. As an example you could specify the seven days of the week as abscissa labels, which would be repeatedly used then.

By passing an empty QStringList you can reset the default behaviour.

See also
labels, setShortLabels

Definition at line 210 of file KChartAbstractAxis.cpp.

void AbstractAxis::setRulerAttributes ( const RulerAttributes a)

Use this to specify the attributes used to paint the axis ruler.

Every axis has a default set of ruler attributes that is exactly the same among them. Use this method to specify your own attributes.

See also
rulerAttributes

Definition at line 199 of file KChartAbstractAxis.cpp.

void AbstractAxis::setShortLabels ( const QStringList list)

Use this to specify your own set of strings, to be used as axis labels, in case the normal labels are too long.

Note
Setting done via setShortLabels will be ignored, if you did not pass a non-empty string list via setLabels too!

By passing an empty QStringList you can reset the default behaviour.

See also
shortLabels, setLabels

Definition at line 224 of file KChartAbstractAxis.cpp.

void AbstractAxis::setTextAttributes ( const TextAttributes a)

Use this to specify the text attributes to be used for axis labels.

By default, the reference area will be set at painting time. It will be the then-valid coordinate plane's parent widget, so normally, it will be the KChart::Chart. Thus the labels of all of your axes in all of your diagrams within that Chart will be drawn in same font size, by default.

textAttributes, setLabels

Definition at line 184 of file KChartAbstractAxis.cpp.

QStringList AbstractAxis::shortLabels ( ) const

Returns a list of strings, that are used as axis labels, as set via setShortLabels.

Note
Setting done via setShortLabels will be ignored, if you did not pass a non-empty string list via setLabels too!
See also
setShortLabels

Definition at line 233 of file KChartAbstractAxis.cpp.

TextAttributes AbstractAxis::textAttributes ( ) const

Returns the text attributes to be used for axis labels.

See also
setTextAttributes

Definition at line 193 of file KChartAbstractAxis.cpp.
