328 If QXYSeries derived series has been added to the chart then QValuesAxes are created as X and Y axes for the series.
329 If QBarSeries or series types derived from it has been added then QBarCategoriesAxis is created as X axis and QValueAxis as Y axis.
330 If there are several QXYSeries derived series added to the chart and no other series type has been added then only one pair of axes is created.
331 If there are sevaral series added of different types then each series gets its own axes pair.
332
333 NOTICE: if there is more than one x and y axes created then no axis is drawn by default and one needs to choose explicitly which axis should be shown.
334
335 Axis specifix to the series can be later obtained from the chart by providing the series as the parameter of axisX(), axisY() function calls.
336 QPieSeries does not create any axes.
