The example shows how to create a simple line chart.
To create a line chart, a QLineSeries instance is needed. Let's create one.
Then we add data to the series. We can use the append() member function or use the stream operator.
To present the data on the chart we need a QChart instance. We add the series to it, create the default axes, and set the title of the chart.
The chart is ready to be shown.
QMainWindow window; window.setCentralWidget(chartView); window.resize(400, 300); window.show();
