6 6 The example shows how to create simple bar chart. Barchart shows the data in sets as separate bars, which are drawn at the x-axis to the position defined by data.

10 10 Data that barchart visualizes, is defined by QBarSet instances. Here we create some sets and append data
11 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.
11 we want to visualize to them. Note that x positions are not in even intervals and this will be reflected in the chart.
12 If x positions aren't defined, then the index of value is assumed to be x position.

15 16 To combine the sets to a chart, we need to create QBarSeries instance. Then we append our barsets to the series.
16 17
17 18 \snippet ../examples/barchart/main.cpp 2
18 19
19 20 Next we create a chart and add the series to it.
21 We also set the title for chart
20 22

23 25 We want to have the legend displayed at the bottom of the chart. Also we turn on the nice numbers algorithm on for y-axis.

27 29 Finally we add the chart onto a view.

15 We create the series and append the sets to it. The grouped barseries groups the data from sets to categories.
16 First value of each set are gropuped together at first category second value to second category and so on.

19 To combine the sets and categories to a chart, we need to create QBarSeries instance. When creating
20 the QBarSeries, the categories must be known. Sets can be added later. For example purposes the sets
21 are added to series here.
