How to remove Extra QPen in my QCustomplot

[Ramkumar Mohan]

I set the timer function and run the graph in real-time plotting point, I have set 2 QPen only, but it shows Extra QPen in my customplot, how to fix it.

This is my code ,

    QString TestName = ui->TestName_Lbl->text();
    QVector<double> xv1(2);
    QVector<double> yv1(2);
    QVector<double> xv2(2);
    QVector<double> yv2(2);
    xv1[0]=xv1[1]=30;
    xv2[0]=xv2[1]=90;
    yv1[0]=yv2[0]=*std::min_element(qv_y.begin() , qv_y.end())-0.25;
    yv1[1]=yv2[1]=*std::max_element(qv_y.begin() , qv_y.end())+0.25;
    ui->customPlot->xAxis->setLabel("Time(S)");
    ui->customPlot->yAxis->setLabel("Abs");
    // set axes ranges, so we see all data:
    ui->customPlot->xAxis->setRange(30, 90);
    ui->customPlot->yAxis->setRange(*std::min_element(qv_y.begin() , qv_y.end())-0.25,*std::max_element(qv_y.begin() , qv_y.end())+0.25);
    ui->customPlot->update();
    ui->customPlot->addGraph();
    ui->customPlot->graph(1)->setPen(QPen(Qt::red,3));
    ui->customPlot->graph(1)->setData(xv1,yv1);
    ui->customPlot->graph(2)->setPen(QPen(Qt::red,8));
    ui->customPlot->graph(2)->setData(xv2,yv2);
    ui->customPlot->replot();
