Detailed Description

Interface for iterating over two QVector<double> objects.

Constructor & Destructor Documentation

QwtPointArrayData::QwtPointArrayData (const QVector< double > & x, constQVector< double > & y)

Constructor

Parameters:

x Array of x values
y Array of y values

See also:

QwtPlotCurve::setData() , QwtPlotCurve::setSamples()

QwtPointArrayData::QwtPointArrayData (const double * x, const double * y,size_t size)

Constructor

Parameters:

x Array of x values
y Array of y values
size Size of the x and y arrays

See also:

QwtPlotCurve::setData() , QwtPlotCurve::setSamples()

Member Function Documentation

QRectF QwtPointArrayData::boundingRect () const [virtual]

Calculate the bounding rectangle. The bounding rectangle is calculated once by iterating over all points and is stored for all following requests.

Returns:

Bounding rectangle

Implements QwtSeriesData< QPointF > .

QPointF QwtPointArrayData::sample (size_t index) const [virtual]

Return the sample at position i

Parameters:

index Index

Returns:

Sample at position i

Implements QwtSeriesData< QPointF > .

size_t QwtPointArrayData::size () const [virtual]

Returns:

Size of the data set

Implements QwtSeriesData< QPointF > .

const QVector< double > & QwtPointArrayData::xData () const

Returns:

Array of the x-values

const QVector< double > & QwtPointArrayData::yData () const

Returns:

Array of the y-values
