Detailed Description#
Model mappers enable using a data model derived from the QAbstractItemModel
class as a data source for a chart. A vertical model mapper is used to create a connection between a data model and a QBoxPlotSeries
object, so that each column in the data model defines a box-and-whiskers item and each row maps to the range and three median values of the box-and-whiskers item.
Both model and series properties can be used to manipulate the data. The model mapper keeps the series and the data model in sync.
The model mapper ensures that all the bar box-and-whiskers items in the box plot series have equal sizes. Therefore, adding or removing a value from a box-and-whiskers item causes the same change to be made in all the box-and-whiskers items in the box plot series.
