Chart display in tabWidget

How to display a chart in tabwidget?

    QLineSeries *series = new QLineSeries();
    for(int i=0;i<size; ++i)
    series->append(p_overpressure[i], alpha[i]);
    QChart *chart = new QChart();
    chart->legend()->hide();
    chart->addSeries(series);
    chart->createDefaultAxes();
    chart->setTitle("График изменения объемной доли газа в зависимости от давления в точке измерения");
    QChartView *chartView = new QChartView(chart);
    chartView->setRenderHint(QPainter::Antialiasing);

In Example so

    QMainWindow window;
    window.setCentralWidget(chartView); // display in the window
    window.resize(400, 300);
    window.show();

Try adding a layout to your tab widget, and attach the chart to that layout.
