Detailed Description

A base class for Charts that are based on an X/Y grid.

Definition at line 32 of file XYChart.h.

Member Enumeration Documentation

◆ Direction

enum class XYChart::Direction
strong

The direction of values on the X axis.

"Start" is defined as the starting direction of the chart, when using a left-to-right language it will be the left side, with a right-to-left language it will be right.

Enumerator
ZeroAtStart 

Zero is at the beginning of the chart, values run from begin to end.

ZeroAtEnd 

Zero is at the end of the chart, values run from end to begin.

Definition at line 46 of file XYChart.h.

Property Documentation

◆ direction

Direction XYChart::direction
readwrite

Which direction this chart's X axis runs.

Definition at line 77 of file XYChart.h.

◆ stacked

bool XYChart::stacked
readwrite

Whether the values of each value source should be stacked.

When true, Y values will be added on top of each other. The precise meaning of this property depends on the specific chart. The default is false.

Definition at line 88 of file XYChart.h.

◆ xRange

RangeGroup * XYChart::xRange
read

The range of values on the X axis.

Definition at line 67 of file XYChart.h.

◆ yRange

RangeGroup * XYChart::yRange
read

The range of values on the Y axis.

Definition at line 72 of file XYChart.h.

Constructor & Destructor Documentation

◆ XYChart()

XYChart::XYChart ( QQuickItem * parent = nullptr)
explicit

Constructor.

Parameters
parentThe QObject parent.

Definition at line 18 of file XYChart.cpp.

◆ ~XYChart()

XYChart::~XYChart ( )
overridedefault

Destructor.

Member Function Documentation

◆ computedRange()

ComputedRange XYChart::computedRange ( ) const

Get the complete, calculated range for this chart.

Definition at line 69 of file XYChart.cpp.

◆ computedRangeChanged()

Q_SIGNAL void XYChart::computedRangeChanged ( )

Emitted whenever the complete range is recalculated.

◆ direction()

XYChart::Direction XYChart::direction ( ) const
virtual

Definition at line 37 of file XYChart.cpp.

◆ setComputedRange()

void XYChart::setComputedRange ( ComputedRange range)
protected

Set the computed range.

Parameters
rangeThe new range.

Definition at line 123 of file XYChart.cpp.

◆ setDirection()

void XYChart::setDirection ( XYChart::Direction newDirection)
virtual

Definition at line 42 of file XYChart.cpp.

◆ setStacked()

void XYChart::setStacked ( bool newStacked)

Definition at line 58 of file XYChart.cpp.

◆ stacked()

bool XYChart::stacked ( ) const

Definition at line 53 of file XYChart.cpp.

◆ updateComputedRange()

void XYChart::updateComputedRange ( )
protectedvirtual

Re-calculate the chart's range.

By default, this will make use of the xRange/yRange properties and calculate a proper range. This method can be overridden by subclasses if some special calculation is needed.

Definition at line 74 of file XYChart.cpp.

◆ xRange()

RangeGroup * XYChart::xRange ( ) const
virtual

Definition at line 27 of file XYChart.cpp.

◆ yRange()

RangeGroup * XYChart::yRange ( ) const
virtual

Definition at line 32 of file XYChart.cpp.
