-                 Then let's create two QLineSeries and tell them to use the data from the model.
+                 First line of the code below creates new line series. Line number two creates an instance of QVXYModelMapper class.
-                 First line of the code below creates new line series. Line number two sets the model as the data source for the series.
+                 Next two lines specifie that x coordinates are taken from the model's column(Qt::Vertical) with index 0 and the y coordinates are taken from the model's column with index 1.
-                 Third line specifies that x coordinates are taken from the model's column(Qt::Vertical) with index 0 and the y coordinates are taken from the model's column with index 1.
+                 To create a connection between the series and the model we set both of those objects to QVXYModelMapper.
                  Finally the series is added to the chart.

                  To avoid setting up the QGraphicsScene we use QChartView class that does it for us. QChart object pointer is used as a parameter of the QChartView constructor.
-                 To make the render look nicer Antialiasing is turned on and the minimum size of the chart is set.
+                 To make the render look nicer Antialiasing is turned on and the minimum size of the chartView widget is set.
