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.
| colorMap | Color Map |
| void QwtPlotSpectroCurve::setColorRange | ( | const QwtInterval & | interval | ) |
Set the value interval, that corresponds to the color map
| interval | interval.minValue() corresponds to 0.0, interval.maxValue() to 1.0 on the color map. |
| void QwtPlotSpectroCurve::setPaintAttribute | ( | PaintAttribute | attribute, |
| bool | on = true |
||
| ) |
Specify an attribute how to draw the curve
| attribute | Paint attribute |
| on | On/Off /sa PaintAttribute, testPaintAttribute() |
| void QwtPlotSpectroCurve::setPenWidth | ( | double | penWidth | ) |
| void QwtPlotSpectroCurve::setSamples | ( | const QVector< QwtPoint3D > & | samples | ) |
Initialize data with an array of samples.
| samples | Vector of points |
| bool QwtPlotSpectroCurve::testPaintAttribute | ( | PaintAttribute | attribute | ) | const |
Return the current paint attributes.
