class UPlotCurve
 

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;
}

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