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 >.

Definition at line 55 of file qwt_point_data.cpp.

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 >.

Definition at line 75 of file qwt_point_data.cpp.

size_t QwtPointArrayData::size ( ) const

virtual

Returns

Size of the data set

Implements QwtSeriesData< QPointF >.

Definition at line 64 of file qwt_point_data.cpp.

const QVector< double > & QwtPointArrayData::xData

(

)

const

Returns

Array of the x-values

Definition at line 81 of file qwt_point_data.cpp.

const QVector< double > & QwtPointArrayData::yData

(

)

const

Returns

Array of the y-values

Definition at line 87 of file qwt_point_data.cpp.
