Public Functions¶

Type	Name
	HistogramFactory (QObject * parent=nullptr) Constructs the factory with the given parent .
Q_INVOKABLE QList< qreal >	decadeEdges (qreal min, qreal max) const Returns the edges from min to__max at 1, 2, ..., 9 times each power of ten: the ticks of a logarithmic axis.
Q_INVOKABLE Histogram	fromCounts (const QList< qreal > & edges, const QList< qreal > & counts) const Wraps data that is already binned: counts has one value per bin between__edges .
Q_INVOKABLE Histogram	fromSamples (const QList< qreal > & samples, const QVariant & bins) const Counts samples into bins.
Q_INVOKABLE Histogram	fromSamples (const QList< qreal > & samples, int binCount, qreal min, qreal max) const Counts samples into__binCount equal bins from__min to__max .
Q_INVOKABLE QList< qreal >	linearEdges (qreal min, qreal max, int binCount) const Returns binCount + 1 equally spaced edges from__min to__max .
Q_INVOKABLE QList< qreal >	logEdges (qreal min, qreal max, int binCount) const Returns binCount + 1 edges from__min to__max , equally spaced on a logarithmic axis.

Detailed Description¶

** **

import QAccelPlot as QAccelPlot

QAccelPlot.BarSeries {
    Component.onCompleted: setData(QAccelPlot.Histogram.fromSamples(samples, 40).bars())
}

C++ code uses the static functions of Histogram instead.

Public Functions Documentation¶

function HistogramFactory¶

Constructs the factory with the given parent .

explicit QAccelPlot::HistogramFactory::HistogramFactory (
    QObject * parent=nullptr
)

function decadeEdges¶

Returns the edges from min to__max at 1, 2, ..., 9 times each power of ten: the ticks of a logarithmic axis.

Q_INVOKABLE QList< qreal > QAccelPlot::HistogramFactory::decadeEdges (
    qreal min,
    qreal max
) const

function fromCounts¶

Wraps data that is already binned: counts has one value per bin between__edges .

Q_INVOKABLE Histogram QAccelPlot::HistogramFactory::fromCounts (
    const QList< qreal > & edges,
    const QList< qreal > & counts
) const

function fromSamples¶

Counts samples into bins.

Q_INVOKABLE Histogram QAccelPlot::HistogramFactory::fromSamples (
    const QList< qreal > & samples,
    const QVariant & bins
) const

bins is either a number of equal bins spanning the finite samples, or a list of finite, strictly increasing edges.

function fromSamples¶

Counts samples into__binCount equal bins from__min to__max .

Q_INVOKABLE Histogram QAccelPlot::HistogramFactory::fromSamples (
    const QList< qreal > & samples,
    int binCount,
    qreal min,
    qreal max
) const

function linearEdges¶

Returns binCount + 1 equally spaced edges from__min to__max .

Q_INVOKABLE QList< qreal > QAccelPlot::HistogramFactory::linearEdges (
    qreal min,
    qreal max,
    int binCount
) const

function logEdges¶

Returns binCount + 1 edges from__min to__max , equally spaced on a logarithmic axis.

Q_INVOKABLE QList< qreal > QAccelPlot::HistogramFactory::logEdges (
    qreal min,
    qreal max,
    int binCount
) const
