Hello!
I want to make several graphics like y=const in one coordinate plane. There is my code:
TimeDiagram::TimeDiagram(QWidget *parent) : QMainWindow(parent), ui(new Ui::TimeDiagram) { ui->setupUi(this); wGraphic = new QCustomPlot(); ui->verticalLayout->addWidget(wGraphic); int max_x=10; int max_y=10; for(int i=0; i < numOfLines;++i) { QVector<double> x(2), y(2); x[0]=0; x[1]=max_x; y[0]= max_y/numOfLines +i+1; y[1]= max_y/numOfLines +i+1; wGraphic->addGraph(wGraphic->xAxis, wGraphic->yAxis); wGraphic->graph(i)->setData(x,y); } wGraphic->replot(); }
Sadly, only coordinate plane appears but no lines. Can you help me?
