QwtPolygonFData - Data class containing a single QwtArray<QwtDoublePoint> object. SYNOPSIS
#include <qwt_data.h> Inherits QwtData. Public Member Functions virtual QwtDoubleRect boundingRect () const virtual QwtData * copy () const const QPolygonF & data () const QwtPolygonFData & operator= (const QwtPolygonFData &) QwtPolygonFData (const QPolygonF &) virtual size_t size () const virtual double x (size_t i) const virtual double y (size_t i) const Detailed Description Data class containing a single QwtArray<QwtDoublePoint> object. Constructor &; Destructor Documentation QwtPolygonFData::QwtPolygonFData (const QPolygonF &polygon) Constructor Parameters: polygon Polygon data See also: QwtPlotCurve::setData() Member Function Documentation QwtDoubleRect QwtData::boundingRect () const [virtual, inherited] Returns the bounding rectangle of the data. If there is no bounding rect, like for empty data the rectangle is invalid: QwtDoubleRect::isValid() == false Warning: This is an slow implementation iterating over all points. It is intended to be overloaded by derived classes. In case of auto scaling boundingRect() is called for every replot, so it might be worth to implement a cache, or use x(0), x(size() - 1) for ordered data ... Reimplemented in QwtArrayData, and QwtCPointerData. QwtData * QwtPolygonFData::copy () const [virtual] Returns: Pointer to a copy (virtual copy constructor) Implements QwtData. const QPolygonF & QwtPolygonFData::data () const Returns: Point array QwtPolygonFData & QwtPolygonFData::operator= (const QwtPolygonFData &data) Assignment. size_t QwtPolygonFData::size () const [virtual] Returns: Size of the data set Implements QwtData. double QwtPolygonFData::x (size_ti) const [virtual] Return the x value of data point i Parameters: i Index Returns: x X value of data point i Implements QwtData. double QwtPolygonFData::y (size_ti) const [virtual] Return the y value of data point i Parameters: i Index Returns: y Y value of data point i Implements QwtData.
