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()

QwtInterval & QwtPlotSpectroCurve::colorRange

(

)

const

Returns:

Value interval, that corresponds to the color map

See also:

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

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

protectedvirtual

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 rect 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.

drawDots()

Implements QwtPlotAbstractSeriesItem.

double QwtPlotSpectroCurve::penWidth

(

)

const

Returns:

Pen width used to draw a dot

See also:

setPenWidth()

int QwtPlotSpectroCurve::rtti ( ) const

virtual

Returns:

QwtPlotItem::Rtti_PlotSpectroCurve

Reimplemented from QwtPlotItem.

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

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

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.

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

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()

void QwtPlotSpectroCurve::setPenWidth

(

double

penWidth

)

Assign a pen width

Parameters:

penWidth

New pen width

See also:

penWidth()

void QwtPlotSpectroCurve::setSamples

(

const QVector< QwtPoint3D > &

samples

)

Initialize data with an array of samples.

Parameters:

samples

Vector of points

bool QwtPlotSpectroCurve::testPaintAttribute

(
