Detailed Description

UPlot is a QWidget to create a plot like MATLAB, and incrementally add new values like a scope using Qt signals/slots. Many customizations can be done at runtime with the right-click menu.

Example:

 #include "utilite/UPlot.h"
 #include <QApplication>

 int main(int argc, char * argv[])
 {
        QApplication app(argc, argv);
        UPlot plot;
        UPlotCurve * curve = plot.addCurve("My curve");
        float y[10] = {0, 1, 2, 3, -3, -2, -1, 0, 1, 2};
        curve->addValues(std::vector<float>(y, y+10));
        plot.showGrid(true);
        plot.setGraphicsView(true);
        plot.show();
        app.exec();
        return 0;
 }

bool UPlot::addCurve	(	UPlotCurve *	curve,
