QLineSeries *series = new QLineSeries();
series->append(0, 6);
series->append(2, 4);
series->append(3, 8);
series->append(7, 4);
series->append(10, 5);
*series << QPointF(11, 1) << QPointF(13, 3) << QPointF(17, 6) << QPointF(18, 3) << QPointF(20, 2);
QChart *chart = new QChart();
chart->legend()->hide();
chart->addSeries(series);
