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

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.


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


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

Which direction this chart's X axis runs.

Definition at line 77 of file XYChart.h.

◆ stacked

bool XYChart::stacked

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

The range of values on the X axis.

Definition at line 67 of file XYChart.h.

◆ yRange

RangeGroup * XYChart::yRange

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)


parentThe QObject parent.

Definition at line 18 of file XYChart.cpp.

◆ ~XYChart()

XYChart::~XYChart ( )


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

Definition at line 37 of file XYChart.cpp.

◆ setComputedRange()

void XYChart::setComputedRange ( ComputedRange range)

Set the computed range.

rangeThe new range.

Definition at line 123 of file XYChart.cpp.

◆ setDirection()

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

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 ( )

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

Definition at line 27 of file XYChart.cpp.

◆ yRange()

RangeGroup * XYChart::yRange ( ) const

Definition at line 32 of file XYChart.cpp.
