             Now lets add some data points to the series.

-                To create line charts, QLineSeries instance is needed. Here we create two line series and we set the color and width of line.

-                We add data to be shown to both series. We can use add() member function or use stream operator.

+                To present the data on the char we need QChart instance. We add the series to it and set the title of the chart.
