Detailed Description

Base class for items on the plot canvas.

A plot item is "something", that can be painted on the plot canvas, or only affects the scales of the plot widget. They can be categorized as:

Representator
A "Representator" is an item that represents some sort of data on the plot canvas. The different representator classes are organized according to the characteristics of the data:
- QwtPlotMarker Represents a point or a horizontal/vertical coordinate
- QwtPlotCurve Represents a series of points
- QwtPlotSpectrogram ( QwtPlotRasterItem ) Represents raster data
- ...
Decorators
A "Decorator" is an item, that displays additional information, that is not related to any data:
- QwtPlotGrid
- QwtPlotScaleItem
- QwtPlotSvgItem
- ...

Depending on the QwtPlotItem::ItemAttribute flags, an item is included into autoscaling or has an entry on the legend.

Before misusing the existing item classes it might be better to implement a new type of plot item ( don't implement a watermark as spectrogram ). Deriving a new type of QwtPlotItem primarily means to implement the YourPlotItem::draw() method.

See also: The cpuplot example shows the implementation of additional plot items.

Member Enumeration Documentation

◆ ItemAttribute

enum QwtPlotItem::ItemAttribute

Plot Item Attributes.

Various aspects of a plot widget depend on the attributes of the attached plot items. If and how a single plot item participates in these updates depends on its attributes.

See also: setItemAttribute(), testItemAttribute(), ItemInterest

Enumerator

Legend

The item is represented on the legend.

AutoScale

The boundingRect() of the item is included in the autoscaling calculation as long as its width or height is >= 0.0.

Margins

The item needs extra space to display something outside its bounding rectangle.

See also: getCanvasMarginHint()

Definition at line 147 of file qwt_plot_item.h.

◆ ItemInterest

enum QwtPlotItem::ItemInterest

Plot Item Interests.

Plot items might depend on the situation of the corresponding plot widget. By enabling an interest the plot item will be notified, when the corresponding attribute of the plot widgets has changed.

See also: setItemAttribute(), testItemAttribute(), ItemInterest

Enumerator

ScaleInterest

The item is interested in updates of the scales

See also: updateScaleDiv()

LegendInterest

The item is interested in updates of the legend ( of other items ) This flag is intended for items, that want to implement a legend for displaying entries of other plot item.

Note: If the plot item wants to be represented on a legend enable QwtPlotItem::Legend instead.

Member Function Documentation

◆ attach()

void QwtPlotItem::attach ( QwtPlot * plot )

Attach the item to a plot.

This method will attach a QwtPlotItem to the QwtPlot argument. It will first detach the QwtPlotItem from any plot from a previous call to attach (if necessary). If a NULL argument is passed, it will detach from any QwtPlot it was attached to.

Parameters

plot	Plot widget

See also: detach()

Definition at line 98 of file qwt_plot_item.cpp.

◆ boundingRect()

QRectF QwtPlotItem::boundingRect ( ) const

virtual

Returns: An invalid bounding rect: QRectF(1.0, 1.0, -2.0, -2.0)

Note: A width or height < 0.0 is ignored by the autoscaler

Reimplemented in QwtPlotZoneItem, QwtPlotVectorField, QwtPlotTradingCurve, QwtPlotShapeItem, QwtPlotSeriesItem, QwtPlotRasterItem, QwtPlotMultiBarChart, QwtPlotMarker, QwtPlotIntervalCurve, QwtPlotHistogram, QwtPlotGraphicItem, and QwtPlotBarChart.

Definition at line 568 of file qwt_plot_item.cpp.

QwtGraphic QwtPlotItem::defaultIcon	(	const QBrush &	brush,
		const QSizeF &	size
	)		const

protected

Return a default icon from a brush.

The default icon is a filled rectangle used in several derived classes as legendIcon().

Parameters

brush	Fill brush
size	Icon size

Returns: A filled rectangle

Definition at line 422 of file qwt_plot_item.cpp.

◆ detach()

void QwtPlotItem::detach ( )

This method detaches a QwtPlotItem from any QwtPlot it has been associated with.

detach() is equivalent to calling attach( NULL )

See also: attach()

Definition at line 119 of file qwt_plot_item.cpp.

◆ draw()

virtual void QwtPlotItem::draw	(	QPainter *	painter,
		const QwtScaleMap &	xMap,
		const QwtScaleMap &	yMap,
		const QRectF &	canvasRect
	)		const

pure virtual

Draw the item.

Parameters

painter	Painter
xMap	Maps x-values into pixel coordinates.
yMap	Maps y-values into pixel coordinates.
canvasRect	Contents rect of the canvas in painter coordinates

Implemented in QwtPlotSpectrogram, QwtPlotShapeItem, QwtPlotSeriesItem, QwtPlotScaleItem, QwtPlotRasterItem, QwtPlotLegendItem, QwtPlotGrid, QwtPlotGraphicItem, QwtPlotMarker, QwtPlotZoneItem, and QwtPlotTextLabel.

◆ getCanvasMarginHint()

void QwtPlotItem::getCanvasMarginHint	(	const QwtScaleMap &	xMap,
		const QwtScaleMap &	yMap,
		const QRectF &	canvasRect,
		double &	left,
		double &	top,
		double &	right,
		double &	bottom
	)		const

virtual

Calculate a hint for the canvas margin.

When the QwtPlotItem::Margins flag is enabled the plot item indicates, that it needs some margins at the borders of the canvas. This is f.e. used by bar charts to reserve space for displaying the bars.

The margins are in target device coordinates ( pixels on screen )

Parameters

xMap	Maps x-values into pixel coordinates.
yMap	Maps y-values into pixel coordinates.
canvasRect	Contents rectangle of the canvas in painter coordinates
left	Returns the left margin
top	Returns the top margin
right	Returns the right margin
bottom	Returns the bottom margin

The default implementation returns 0 for all margins

See also: QwtPlot::getCanvasMarginsHint(), QwtPlot::updateCanvasMargins()

Reimplemented in QwtPlotAbstractBarChart.

Definition at line 595 of file qwt_plot_item.cpp.

◆ isVisible()

bool QwtPlotItem::isVisible ( ) const

Returns: true if visible

See also: setVisible(), show(), hide()

Definition at line 470 of file qwt_plot_item.cpp.

◆ itemChanged()

void QwtPlotItem::itemChanged ( )

virtual

Update the legend and call QwtPlot::autoRefresh() for the parent plot.

See also: QwtPlot::legendChanged(), QwtPlot::autoRefresh()

Definition at line 481 of file qwt_plot_item.cpp.

◆ legendChanged()

void QwtPlotItem::legendChanged ( )

virtual

See also: QwtPlot::updateLegend(), itemChanged()

Definition at line 491 of file qwt_plot_item.cpp.

◆ legendData()

QList< QwtLegendData > QwtPlotItem::legendData ( ) const

virtual

Return all information, that is needed to represent the item on the legend.

Most items are represented by one entry on the legend showing an icon and a text, but f.e. QwtPlotMultiBarChart displays one entry for each bar.

QwtLegendData is basically a list of QVariants that makes it possible to overload and reimplement legendData() to return almost any type of information, that is understood by the receiver that acts as the legend.

The default implementation returns one entry with the title() of the item and the legendIcon().

Returns: Data, that is needed to represent the item on the legend

See also: title(), legendIcon(), QwtLegend, QwtPlotLegendItem

Reimplemented in QwtPlotMultiBarChart, and QwtPlotBarChart.

Definition at line 626 of file qwt_plot_item.cpp.

The default implementation returns an invalid icon

Parameters

index	Index of the legend entry ( usually there is only one )
size	Icon size

See also: setLegendIconSize(), legendData()

Reimplemented in QwtPlotVectorField, QwtPlotTradingCurve, QwtPlotShapeItem, QwtPlotMultiBarChart, QwtPlotMarker, QwtPlotIntervalCurve, QwtPlotHistogram, QwtPlotCurve, and QwtPlotBarChart.

		const QwtScaleMap &	yMap
	)		const

Parameters

xMap	Maps x-values into pixel coordinates.
yMap	Maps y-values into pixel coordinates.

Returns: Bounding paint rectangle of the scale maps, not normalized

Definition at line 720 of file qwt_plot_item.cpp.

◆ renderThreadCount()

uint QwtPlotItem::renderThreadCount ( ) const

Returns: Number of threads to be used for rendering. If numThreads() is set to 0, the system specific ideal thread count is used.

Definition at line 360 of file qwt_plot_item.cpp.

◆ rtti()

int QwtPlotItem::rtti ( ) const

virtual

Return rtti for the specific class represented. QwtPlotItem is simply a virtual interface class, and base classes will implement this method with specific rtti values so a user can differentiate them.

Update the item, when the axes of plot have changed. The default implementation does nothing, but items that depend on the scale division (like QwtPlotGrid()) have to reimplement updateScaleDiv()

updateScaleDiv() is only called when the ScaleInterest interest is enabled. The default implementation does nothing.

Parameters

xScaleDiv	Scale division of the x-axis
yScaleDiv	Scale division of the y-axis
