Member Function Documentation

const QwtColorMap * QwtPlotSpectroCurve::colorMap ( ) const

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

See also:: setColorMap(), setColorRange(), QwtColorMap::color()

Definition at line 161 of file qwt_plot_spectrocurve.cpp.

QwtInterval & QwtPlotSpectroCurve::colorRange ( ) const

Returns:: Value interval, that corresponds to the color map

See also:: setColorRange(), setColorMap(), QwtColorMap::color()

Definition at line 189 of file qwt_plot_spectrocurve.cpp.

void QwtPlotSpectroCurve::drawDots	(	QPainter *	painter,
		const QwtScaleMap &	xMap,
		const QwtScaleMap &	yMap,
		const QRectF &	canvasRect,
		int	from,
		int	to
	)		const `[protected, 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.

		const QwtScaleMap &	xMap,
		const QwtScaleMap &	yMap,
		const QRectF &	canvasRect,
		int	from,

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

Implements QwtPlotSeriesItem.

Definition at line 236 of file qwt_plot_spectrocurve.cpp.

void QwtPlotSpectroCurve::init ( ) [private]

Initialize data members.

Definition at line 68 of file qwt_plot_spectrocurve.cpp.

double QwtPlotSpectroCurve::penWidth ( ) const

Returns:: Pen width used to draw a dot

See also:: setPenWidth()

Definition at line 218 of file qwt_plot_spectrocurve.cpp.

int QwtPlotSpectroCurve::rtti ( ) const [virtual]

Returns:: QwtPlotItem::Rtti_PlotSpectroCurve

Reimplemented from QwtPlotItem.

Definition at line 80 of file qwt_plot_spectrocurve.cpp.

void QwtPlotSpectroCurve::setColorMap ( QwtColorMap * colorMap )

Change the color map

Often it is useful to display the mapping between intensities and colors as an additional plot axis, showing a color bar.

Parameters:

colorMap Color Map

See also:: colorMap(), setColorRange(), QwtColorMap::color(), QwtScaleWidget::setColorBarEnabled(), QwtScaleWidget::setColorMap()

Definition at line 145 of file qwt_plot_spectrocurve.cpp.

void QwtPlotSpectroCurve::setColorRange ( const QwtInterval & interval )

Set the value interval, that corresponds to the color map

Parameters:

interval interval.minValue() corresponds to 0.0, interval.maxValue() to 1.0 on the color map.

See also:: colorRange(), setColorMap(), QwtColorMap::color()

Definition at line 174 of file qwt_plot_spectrocurve.cpp.

void QwtPlotSpectroCurve::setPaintAttribute	(	PaintAttribute	attribute,
		bool	on = `true`
	)

Specify an attribute how to draw the curve

Parameters:

attribute	Paint attribute
on	On/Off /sa PaintAttribute, testPaintAttribute()

Definition at line 92 of file qwt_plot_spectrocurve.cpp.

void QwtPlotSpectroCurve::setPenWidth ( double penWidth )

Assign a pen width

Parameters:

penWidth New pen width

See also:: penWidth()

Definition at line 200 of file qwt_plot_spectrocurve.cpp.

void QwtPlotSpectroCurve::setSamples ( const QVector< QwtPoint3D > & samples )

Initialize data with an array of samples.

Parameters:

samples Vector of points

Definition at line 113 of file qwt_plot_spectrocurve.cpp.

void QwtPlotSpectroCurve::setSamples ( QwtSeriesData< QwtPoint3D > * data )

Assign a series of samples

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 128 of file qwt_plot_spectrocurve.cpp.

bool QwtPlotSpectroCurve::testPaintAttribute ( PaintAttribute attribute ) const

Returns:: True, when attribute is enabled

See also:: PaintAttribute, setPaintAttribute()

Definition at line 104 of file qwt_plot_spectrocurve.cpp.
