     The barsets are used in same way in all barcharts.

+    Data, which the barchart visualizes, is defined by the QBarSet instances. Here we create the sets and append data
     to them. The data is appended here with << operator. Alternatively the append method could be used.

     We create the series and append the barsets to it. The series takes ownership of the barsets. The series groups the data from sets to categories.
-    First values of each set are grouped together at first category second value to second category and so on.

-	To have categories displayed on axis, we need to create a QBarCategoryAxis for that. Here we create a category axis with list of categories and
-	set it to be the x-axis of the chart. The chart takes ownership of axis. For y-axis we use default axis, which is created and scaled to series data
-	by calling createDefaultAxes of the chart. Note that the call for createDefaultAxes must be before we set the category axis. Otherwise the default axis will
-	override the category axis.
