Detailed Description
A box plot series acts as a container for box-and-whiskers items. Items from multiple series are grouped into categories according to their index value.
The QBarCategoryAxis class is used to add the categories to the chart's axis. Category labels have to be unique. If the same category label is defined for several box-and-whiskers items, only the first one is drawn.
See the box-and-whiskers chart example to learn how to create a box-and-whiskers chart.
