QwtDoubleRect QwtArrayData::boundingRect () const [virtual]

Returns the bounding rectangle of the data. If there is no bounding rect, like for empty data the rectangle is invalid: QwtDoubleRect::isValid() == FALSE

Reimplemented from QwtData.

Definition at line 156 of file qwt_data.cpp.

References size().  

QwtData * QwtArrayData::copy () const [virtual]

Return a pointer to a copy (virtual copy constructor)

Implements QwtData.

Definition at line 146 of file qwt_data.cpp.

References QwtArrayData().  

QwtArrayData & QwtArrayData::operator= (const QwtArrayData &)

Assignment.

Definition at line 121 of file qwt_data.cpp.

References d_x, and d_y.  

size_t QwtArrayData::size () const [virtual]

Return the size of the data set

Implements QwtData.

Definition at line 131 of file qwt_data.cpp.

Referenced by boundingRect().  

double QwtArrayData::x (size_t i) const [virtual]

Return the x value of data point i

Parameters:

i Index

Returns:

x X value of data point i

Implements QwtData.

Definition at line 136 of file qwt_data.cpp.  

double QwtArrayData::y (size_t i) const [virtual]

Return the y value of data point i

Parameters:

i Index

Returns:

y Y value of data point i
