10 To create spline chart we need to put our data into QSplineSeries. QSplineSeries automatically calculates spline segment control points that are needed to properly draw the spline.

22 The data series has been populated. To display it on a chart we create QChartView object and add the data series to it. We also set the ranges on both axises, so that our chart is fully visible and there is some excess of space for adding more data points.

26 Then we add two buttons for adding and removing data points. Buttons clicked() signals are connected to handler functions.
26 Then we created a QChartView object with QChart as a parameter. This way we don't need to create QGraphicsView scene ourselves. We also set the Antialiasing on to have the rendered lines look nicer.
