Member Function Documentation

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 237 of file qwt_data.cpp. References size().

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

Returns: Pointer to a copy (virtual copy constructor) Implements QwtData. Definition at line 227 of file qwt_data.cpp. References QwtArrayData().

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

Assignment. Definition at line 174 of file qwt_data.cpp. References d_x, and d_y.

size_t QwtArrayData::size (   )  const [virtual]

Returns: Size of the data set Implements QwtData. Definition at line 185 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 196 of file qwt_data.cpp.

const QwtArray< double > & QwtArrayData::xData (   )  const

Returns: Array of the x-values Definition at line 213 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 Implements QwtData. Definition at line 207 of file qwt_data.cpp.

const QwtArray< double > & QwtArrayData::yData (   )  const

Returns: Array of the y-values Definition at line 219 of file qwt_data.cpp.
