r1859 The barsets are used in same way in all barcharts.
To illustrate difference between various barcharts, we use same data in examples.

r1618 Data that barchart visualizes, is defined by QBarSet instances. Here we create the sets and append data

r1859 Here we create the chart object and add the series to it. We set the title for chart with setTitle and then turn on animations of the series by calling
setAnimationOptions(QChart::SeriesAnimations)

r1859 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.

r1859 We also want to show the legend. To do that, we get the legend pointer from chart and set it to visible. We also place the legend to bottom of the chart by setting it's alignment
to Qt::AlignBottom.
