C++ (Cpp) setContourLevels Examples

Example #1

File: Spectrogram.cpp Project: BackupTheBerlios/qtiplot-svn

Spectrogram::Spectrogram(Graph *graph, Matrix *m):
	QwtPlotSpectrogram(QString(m->objectName())),
	d_graph(graph),
	d_matrix(m),
	color_axis(QwtPlot::yRight),
	color_map_policy(Default),
	color_map(QwtLinearColorMap()),
	d_show_labels(true),
	d_labels_color(Qt::black),
	d_labels_font(QFont()),
	d_white_out_labels(false),
	d_labels_angle(0.0),
	d_labels_x_offset(0),
	d_labels_y_offset(0),
	d_selected_label(NULL),
	d_use_matrix_formula(false),
	d_color_map_pen(false),
	d_impose_range(false)
{
	setData(MatrixData(m));

	double step = fabs(data().range().maxValue() - data().range().minValue())/5.0;

	QwtValueList contourLevels;
	for ( double level = data().range().minValue() + step;
		level < data().range().maxValue(); level += step )
		contourLevels += level;

	setContourLevels(contourLevels);
}

Example #2

File: Spectrogram.cpp Project: BackupTheBerlios/qtiplot-svn

void Spectrogram::setLevelsNumber(int levels)
{
double step = fabs(data().range().maxValue() - data().range().minValue())/(double)levels;

QwtValueList contourLevels;
for ( double level = data().range().minValue() + 0.5*step;
	level < data().range().maxValue(); level += step )
    contourLevels += level;

setContourLevels(contourLevels);
}

Example #3

File: plotzoz.cpp Project: Kansept/SanPasport

PlotSpectr::PlotSpectr()
{
    setRenderThreadCount(0);  // use system specific thread count

    QList<double> contourLevels;
    contourLevels += 0.99;
    setContourLevels( contourLevels );

    setAlpha(0);
    setDisplayMode( QwtPlotSpectrogram::ContourMode, true );
    setCachePolicy( QwtPlotRasterItem::PaintCache );
    setRenderHint(QwtPlotItem::RenderAntialiased);
}

Example #4

File: Spectrogram.cpp Project: BackupTheBerlios/qtiplot-svn

{
	if (levels <= 0)
		return;

	double step = fabs(range().maxValue() - range().minValue())/(double)levels;

	QwtValueList contourLevels;
	for ( double level = range().minValue() + 0.5*step;
		level < range().maxValue(); level += step )
		contourLevels += level;

	setContourLevels(contourLevels);
}
