QVHistogramPlot (const QString name=QString(), bool time=true, int step=10, double maxim=0, double minim=0, QWidget *parent=0) | |
Constructs a QVHistogramPlot with a given string identifier, and a iteration's parameters. | |
bool | linkProperty (QVWorker &worker, const QString propertyName) |
Links properties from workers. |
This class lets us plot graphs for a QList<double> worker's output property. First, we need a worker with a QList<double> output property, like this:
class MyWorker: public QVWorker { public: MyWorker(QString name): QVWorker(name) { addProperty< QVImage<uChar,1> >("Input image", inputFlag|outputFlag); addProperty< QVImage<uChar,1> >("Output image", outputFlag); addProperty<QList<double> >("FirstRow", outputFlag); ...
And then, in the main function, we can create a QVHistogramPlot and link it with that property, like this:
... MyWorker myWorker("worker"); QVHistogramPlot histPlot("histFirstRow", false, 10, 300); histPlot.linkProperty(myWorker, "FirstRow"); ...
Showing us a graph window like this:

Constructs a QVHistogramPlot with a given string identifier, and a iteration's parameters.
name | Identifier for the object to be created. | |
time | True if the iterations are based on clock time (in second hundredths), and false if they are based on worker's iterations. | |
step | Set the base measure to plot's iterations ratio. | |
maxim | The left axis maximum value shown, if it is 0, the maximum value is auto scale. | |
minim | The left axis minimum value shown, it must be less than maximum value. | |
parent | Identifier for the parent widget. |

Links properties from workers.
This method safely links properties from workers in a thread safe manner. If the iterations are based on worker's iterations (time == false), the worker must be synchronised with previous linked workers. Only can be linked QList<double> properties.

worker | The source QVWorker. | |
propertyName | Identifying QString for the source property. |
