Member Function Documentation

double QwtPlotVectorField::arrowLength ( double magnitude ) const

virtual

Computes length of the arrow in screen coordinate units based on its magnitude. Default implementation simply scales the vector using the magnitudeScaleFactor property. Re-implement this function to provide special handling for zero/non-zero magnitude arrows, or impose minimum/maximum arrow length limits.

Returns: Length of arrow to be drawn in dependence of vector magnitude.

See also: setMagnitudeScaleFactor

Definition at line 568 of file qwt_plot_vectorfield.cpp.

QRectF QwtPlotVectorField::boundingRect ( ) const

virtual

Returns: An invalid bounding rect: QRectF(1.0, 1.0, -2.0, -2.0)

Note: A width or height < 0.0 is ignored by the autoscaler

Reimplemented from QwtPlotSeriesItem.

Definition at line 594 of file qwt_plot_vectorfield.cpp.

QBrush QwtPlotVectorField::brush ( ) const

Definition at line 349 of file qwt_plot_vectorfield.cpp.

const QwtColorMap * QwtPlotVectorField::colorMap ( ) const

Returns: Color Map used for mapping the intensity values to colors

	)		const

virtual

Draw a subset of the points

Parameters

painter	Painter
xMap	Maps x-values into pixel coordinates.
yMap	Maps y-values into pixel coordinates.
canvasRect	Contents rectangle of the canvas
from	Index of the first sample to be painted
to	Index of the last sample to be painted. If to < 0 the series will be painted to its last sample.

setSamples() is just a wrapper for setData() without any additional value - beside that it is easier to find for the developer.

Parameters

data Data

Warning: The item takes ownership of the data object, deleting it when its not used anymore.

Definition at line 509 of file qwt_plot_vectorfield.cpp.

void QwtPlotVectorField::setSymbol ( QwtVectorFieldSymbol * symbol )
