| 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 |
Definition at line 147 of file qwt_plot_spectrocurve.cpp.
| 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::setSamples | ( | const QVector< QwtPoint3D > & | samples | ) |
Initialize data with an array of samples.
| samples | Vector of points |
Definition at line 115 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.
