QChart is a QGraphicsWidget that you can show in a QGraphicsScene. It manages the graphical

axes. If you simply want to show a chart in a layout, you can use the

convenience class QChartView instead of QChart.

If there are several QXYSeries derived series added to the chart and no series of other types have been added, then only one pair of axes is created.

If there are several series of different types added to the chart, then each series gets its own axes pair.

The axes specific to the series can be later obtained from the chart by providing the series as the parameter for axes() function call.

QPieSeries does not create any axes.
