Member Function Documentation

boundingRect()

QRectF QwtSeriesWrapper::boundingRect ( ) const

overridevirtual

Calculate the bounding rect of all samples

The bounding rect is necessary for autoscaling and can be used for a couple of painting optimizations.

qwtBoundingRect(...) offers slow implementations iterating over the samples. For large sets it is recommended to implement something faster f.e. by caching the bounding rectangle.

Returns

Bounding rectangle

Implements QwtSeriesData< QPointF >.

Reimplemented in QwtTimeseries.

Definition at line 139 of file timeseries_qwt.cpp.

getVisualizationRangeX()

RangeOpt QwtSeriesWrapper::getVisualizationRangeX ( )

virtual

Reimplemented in QwtTimeseries, and PointSeriesXY.

Definition at line 195 of file timeseries_qwt.cpp.

getVisualizationRangeY()

RangeOpt QwtSeriesWrapper::getVisualizationRangeY ( Range  range_X )

virtual

Reimplemented in QwtTimeseries, and PointSeriesXY.

Definition at line 14 of file timeseries_qwt.cpp.

plotData()

const PlotDataBase< double, double > * QwtSeriesWrapper::plotData ( ) const

virtual

Reimplemented in PointSeriesXY.

Definition at line 220 of file timeseries_qwt.cpp.

sample()

QPointF QwtSeriesWrapper::sample ( size_t  i ) const

overridevirtual

Return a sample

Parameters

i

Index

Returns

Sample at position i

size()

size_t QwtSeriesWrapper::size ( ) const

overridevirtual
