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;
 }

Member Function Documentation

UPlotCurve* UPlot::addCurve	(	const QString &	curveName,
		const QColor &	color = QColor()
	)

Add a curve. The returned curve doesn't need to be deallocated (UPlot keeps the ownership).

bool UPlot::addCurve	(	UPlotCurve *	curve,
		bool	ownershipTransferred = true
	)

Add a curve. Ownership is transferred to UPlot if ownershipTransferred=true.

UPlotCurveThreshold* UPlot::addThreshold	(	const QString &	name,
		float	value,
		Qt::Orientation	orientation = Qt::Horizontal
	)

Add a threshold to the plot.

void UPlot::clearData

(

)

[slot]

Clear all curves' data.

QStringList UPlot::curveNames

(

)

Get all curve names.

void UPlot::removeCurve

(

const UPlotCurve *

curve

)

[slot]

Remove a curve. If UPlot is the parent of the curve, the curve is deleted.
