Detailed Description

Polar coordinate plane.

Definition at line 33 of file KChartPolarCoordinatePlane.h.

Member Function Documentation

void PolarCoordinatePlane::addDiagram ( AbstractDiagram diagram)
overridevirtual

Adds a diagram to this coordinate plane.

Parameters
diagramThe diagram to add.
See also
replaceDiagram, takeDiagram

Reimplemented from KChart::AbstractCoordinatePlane.

Definition at line 58 of file KChartPolarCoordinatePlane.cpp.

const GridAttributes KChart::PolarCoordinatePlane::gridAttributes ( bool  circular) const
Returns
The attributes used for grid lines drawn in circular direction (or in sagittal direction, resp.).
Note
This function always returns a valid set of grid attributes: If no special grid attributes were set for this direction the global attributes are returned, as returned by AbstractCoordinatePlane::globalGridAttributes.
See also
setGridAttributes
resetGridAttributes
AbstractCoordinatePlane::globalGridAttributes
hasOwnGridAttributes

Definition at line 334 of file KChartPolarCoordinatePlane.cpp.

bool KChart::PolarCoordinatePlane::hasOwnGridAttributes ( bool  circular) const
Returns
Returns whether the grid attributes have been set for the respective direction via setGridAttributes( bool circular ).

If false, the grid will use the global attributes set by AbstractCoordinatePlane::globalGridAttributes (or the default attributes, resp.)

See also
setGridAttributes
resetGridAttributes
AbstractCoordinatePlane::globalGridAttributes

Definition at line 369 of file KChartPolarCoordinatePlane.cpp.

void PolarCoordinatePlane::layoutDiagrams ( )
overrideprotectedvirtual

Distribute the available space among the diagrams and axes.

Implements KChart::AbstractCoordinatePlane.

Definition at line 145 of file KChartPolarCoordinatePlane.cpp.

void PolarCoordinatePlane::paint ( QPainter painter)
overridevirtual

reimpl

Implements KChart::AbstractLayoutItem.

Definition at line 69 of file KChartPolarCoordinatePlane.cpp.

void KChart::PolarCoordinatePlane::resetGridAttributes ( bool  circular)

Reset the attributes to be used for grid lines drawn in circular direction (or in sagittal direction, resp.).

By calling this method you specify that the global attributes set by AbstractCoordinatePlane::setGlobalGridAttributes be used.

See also
setGridAttributes, gridAttributes
AbstractCoordinatePlane::globalGridAttributes
hasOwnGridAttributes

Definition at line 327 of file KChartPolarCoordinatePlane.cpp.

void KChart::PolarCoordinatePlane::setGridAttributes ( bool  circular,
const GridAttributes a 
)

Set the attributes to be used for grid lines drawn in circular direction (or in sagittal direction, resp.).

To disable circular grid painting, for example, your code should like this:

GridAttributes ga = plane->gridAttributes( bool );
ga.setGridVisible( false );
plane-setGridAttributes( bool, ga );
Note
setGridAttributes overwrites the global attributes that were set by AbstractCoordinatePlane::setGlobalGridAttributes. To re-activate these global attributes you can call resetGridAttributes.

resetGridAttributes, gridAttributes
AbstractCoordinatePlane::setGlobalGridAttributes
hasOwnGridAttributes

Definition at line 314 of file KChartPolarCoordinatePlane.cpp.

void PolarCoordinatePlane::setStartPosition ( qreal  degrees)

Specify the rotation of the coordinate plane.

In a pie diagram this indicates the position where the first pie starts, in a polar diagram it specifies the Zero position of the circular axis:

Definition at line 224 of file KChartPolarCoordinatePlane.cpp.

void PolarCoordinatePlane::setZoomCenter ( const QPointF center)
overridevirtual

Set the point (in value coordinates) to be used as the center point in zoom operations.

Parameters
centerThe point to use.

Reimplemented from KChart::AbstractCoordinatePlane.

Definition at line 293 of file KChartPolarCoordinatePlane.cpp.

void PolarCoordinatePlane::setZoomFactors ( qreal  factorX,
qreal  factorY 
)
overridevirtual

Sets both zoom factors in one go.

See also
setZoomFactorX,setZoomFactorY

Reimplemented from KChart::AbstractCoordinatePlane.

Definition at line 258 of file KChartPolarCoordinatePlane.cpp.

void PolarCoordinatePlane::setZoomFactorX ( qreal  factor)
overridevirtual

Sets the zoom factor in horizontal direction, that is applied to all coordinate transformations.

Parameters
factorThe new zoom factor

Reimplemented from KChart::AbstractCoordinatePlane.

Definition at line 264 of file KChartPolarCoordinatePlane.cpp.

void PolarCoordinatePlane::setZoomFactorY ( qreal  factor)
overridevirtual

Sets the zoom factor in vertical direction, that is applied to all coordinate transformations.

Parameters
factorThe new zoom factor

Reimplemented from KChart::AbstractCoordinatePlane.

Definition at line 275 of file KChartPolarCoordinatePlane.cpp.

qreal PolarCoordinatePlane::startPosition ( ) const

Retrieve the rotation of the coordinate plane.

setStartPosition

Definition at line 237 of file KChartPolarCoordinatePlane.cpp.

const QPointF PolarCoordinatePlane::translate ( const QPointF diagramPoint) const
overridevirtual

Translate the given point in value space coordinates to a position in pixel space.

Parameters
diagramPointThe point in value coordinates.
Returns
The translated point.

Implements KChart::AbstractCoordinatePlane.

Definition at line 191 of file KChartPolarCoordinatePlane.cpp.

QPointF PolarCoordinatePlane::zoomCenter ( ) const
overridevirtual
Returns
The center point (in value coordinates) of the coordinate plane, that is used for zoom operations.

Reimplemented from KChart::AbstractCoordinatePlane.

Definition at line 286 of file KChartPolarCoordinatePlane.cpp.

qreal PolarCoordinatePlane::zoomFactorX ( ) const
overridevirtual
Returns
The zoom factor in horizontal direction, that is applied to all coordinate transformations.

Reimplemented from KChart::AbstractCoordinatePlane.

Definition at line 244 of file KChartPolarCoordinatePlane.cpp.

qreal PolarCoordinatePlane::zoomFactorY ( ) const
overridevirtual
Returns
The zoom factor in vertical direction, that is applied to all coordinate transformations.
