                  Data that barchart visualizes, is defined by QBarSet instances. Here we create some sets and append data
-                 we want to visualize to them. Note that first and third QPointF in each set have smaller intervals at their x coordinates. This will be reflected in the chart.
+                 we want to visualize to them. Note that x positions are not in even intervals and this will be reflected in the chart.
+             	If x positions aren't defined, then the index of value is assumed to be x position.

                  Next we create a chart and add the series to it.
+             	We also set the title for chart

                  The example shows how to create simple bar chart. GroupedBarChart shows the data in sets as separate bars, which are grouped in categories.

-                 First we define categories.
+                 Data that groupedbarchart visualizes, is defined by QBarSet instances. Here we create the sets and append data
+                 to them.

-                 we want to visualize to them.
+                 We create the series and append the sets to it. The grouped barseries groups the data from sets to categories.
+             	First value of each set are gropuped together at first category second value to second category and so on.
                  \snippet ../examples/groupedbarchart/main.cpp 2
-                 To combine the sets and categories to a chart, we need to create QBarSeries instance. When creating
-             	the QBarSeries, the categories must be known. Sets can be added later. For example purposes the sets
-             	are added to series here.
+                 Then we create a chart and add the series to it.
                  \snippet ../examples/groupedbarchart/main.cpp 3
-                 Then we create a chart and add the series to it.
+             	We define the categories here and add them to the x-axis.
