Detailed Description

A chart with one or more diagrams.

The Chart class represents a drawing consisting of one or more diagrams and various optional elements such as legends, axes, text boxes, headers or footers. It takes ownership of all these elements when they are assigned to it. Each diagram is associated with a coordinate plane, of which the chart can have more than one. The coordinate planes (and thus the associated diagrams) can be laid out in various ways.

The Chart class makes heavy use of the Qt Interview framework for model/view programming, and thus requires data to be presented to it in a QAbstractItemModel compatible way. For many simple charts, especially if the visualized data is static, KChart::Widget provides an abstracted interface, that hides the complexity of Interview to a large extent.

void Chart::paint ( QPainter painter,
const QRect rect 
)

Paints all the contents of the chart.

Use this method to make KChart draw into your QPainter.

Note
Any global leading settings will be used by the paint method too, so make sure to set them to zero, if you want the drawing to have the exact size of the target rectangle.
Parameters
painterThe painter to be drawn into.
rectThe rectangle to be filled by the Chart's drawing.

void Chart::paintEvent ( QPaintEvent event)
overrideprotectedvirtual

Draws the background and frame, then calls paint().

In most cases there is no need to override this method in a derived class, but if you do, do not forget to call paint().

void KChart::Chart::propertiesChanged ( )
signal

Emitted upon change of a property of the Chart or any of its components.

void Chart::replaceCoordinatePlane ( AbstractCoordinatePlane plane,
AbstractCoordinatePlane oldPlane = nullptr 
)

Replaces the old coordinate plane, or appends the plane, it there is none yet.

Parameters
planeThe coordinate plane to be used instead of the old plane. This parameter must not be zero, or the method will do nothing.
oldPlaneThe coordinate plane to be removed by the new plane. This plane will be deleted automatically. If the parameter is omitted, the very first coordinate plane will be replaced. In case, there was no plane yet, the new plane will just be added.
Note
If you want to re-use the old coordinate plane, call takeCoordinatePlane and addCoordinatePlane, instead of using replaceCoordinatePlane.

void Chart::replaceHeaderFooter ( HeaderFooter headerFooter,
HeaderFooter oldHeaderFooter = nullptr 
)

Replaces the old header (or footer, resp.), or appends the new header or footer, it there is none yet.

Parameters
headerFooterThe header or footer to be used instead of the old one. This parameter must not be zero, or the method will do nothing.
oldHeaderFooterThe header or footer to be removed by the new one. This header or footer will be deleted automatically. If the parameter is omitted, the very first header or footer will be replaced. In case, there was no header and no footer yet, the new header or footer will just be added.
Note
If you want to re-use the old header or footer, call takeHeaderFooter and addHeaderFooter, instead of using replaceHeaderFooter.

void Chart::replaceLegend ( Legend legend,
Legend oldLegend = nullptr 
)

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

Parameters
legendThe legend to be used instead of the old one. This parameter must not be zero, or the method will do nothing.
oldLegendThe legend to be removed by the new one. This legend will be deleted automatically. If the parameter is omitted, the very first legend will be replaced. In case, there was no legend yet, the new legend will just be added.

If you want to re-use the old legend, call takeLegend and addLegend, instead of using replaceLegend.

Note
Whenever addLegend is called the font sizes used by the Legend are set to relative and they get coupled to the Chart's size, with their relative values being 20 for the item texts and 24 to the title text. So if you want to use custom font sizes for the Legend make sure to set them after calling addLegend.

void Chart::resizeEvent ( QResizeEvent event)
overrideprotectedvirtual

Adjusts the internal layout when the chart is resized.

Reimplemented from QWidget.

Definition at line 1383 of file KChartChart.cpp.

void Chart::setBackgroundAttributes ( const BackgroundAttributes a)

Specify the background attributes to be used, by default there is no background.

To set a light blue background, you could do something like this:

KChart::BackgroundAttributes backgroundAttrs( my_chart->backgroundAttributes() );
backgroundAttrs.setVisible( true );
backgroundAttrs.setBrush( QColor(0xd0,0xd0,0xff) );
my_chart->setBackgroundAttributes( backgroundAttrs );

Definition at line 1186 of file KChartChart.cpp.

void Chart::setCoordinatePlaneLayout ( QLayout layout)

Set the coordinate plane layout that should be used as model for the internal used layout.

The layout needs to be an instance of QHBoxLayout or QVBoxLayout.

Definition at line 1197 of file KChartChart.cpp.

void Chart::setFrameAttributes ( const FrameAttributes a)

Specify the frame attributes to be used, by default is it a thin black line.

To hide the frame line, you could do something like this:

KChart::FrameAttributes frameAttrs( my_chart->frameAttributes() );
frameAttrs.setVisible( false );
my_chart->setFrameAttributes( frameAttrs );

void Chart::setGlobalLeading ( int  left,
int  top,
int  right,
int  bottom 
)

Set the padding between the margin of the widget and the area that the contents are drawn into.

Parameters
leftThe padding on the left side.
topThe padding at the top.
rightThe padding on the left hand side.
bottomThe padding on the bottom.
Note
Using previous versions of KD Chart you might have called setGlobalLeading() to make room for long Abscissa labels (or for an overlapping top label of an Ordinate axis, resp.) that would not fit into the normal axis area. This is no longer needed because KD Chart now is using hidden auto-spacer items reserving as much free space as is needed for axes with overlaping content at the respective sides.

bool KChart::Chart::useNewLayoutSystem ( ) const

useNewLayoutSystem Be very careful activating the new layout system, its still experimental and works only if the user knows what he is doing.

The reason is that the system does not prevent the user from creating sharing graphs that are not layoutable in a plane and still needs assistance from the user.
