Member Function Documentation

QRectF QwtPointSeriesData::boundingRect

(

)

const [virtual]

Calculate the bounding rect.

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

Returns:

Bounding rectangle

Implements QwtSeriesData< QPointF >.

virtual QPointF QwtArraySeriesData< QPointF >::sample

(

size_t

i

)

const [virtual, inherited]

Return a sample

Parameters:

i

Index

Returns:

Sample at position i

Implements QwtSeriesData< QPointF >.

virtual size_t QwtArraySeriesData< QPointF >::size

(

)

const [virtual, inherited]

Returns:

Number of samples

Implements QwtSeriesData< QPointF >.
