Now let's add some data points to the series.
The data series has been populated. To display it on a chart we create a QChart object and add the data series to it. We also set the title and the values range on the y-axis, so that our chart's visibility is better.
Finally, we set the QChartView as the windows's central widget.
QMainWindow window; window.setCentralWidget(chartView); window.resize(400, 300); window.show();
