/*!
* \class QItemModelBarDataMapping
* \inmodule QtDataVis3D
* \brief Data model mapping for Q3DBars.
* \since 1.0.0
*
* QItemModelBarDataMapping is used to map roles of QAbstractItemModel to rows, columns, and values
* of Q3DBars. There are two ways to use QItemModelBarDataMapping:
*
* 1) By default, the QItemModelBarDataMapping will map the rows and columns of QAbstractItemModel
* to rows and columns of Q3DBars, and uses the value returned for Qt::DisplayRole as bar value.
* The value role to be used can be redefined if Qt::DisplayRole is not suitable.
*
* 2) For models that do not have data already neatly sorted into rows and columns, such as
* QAbstractListModel based models, you can define a list of categories for both rows and columns,
* and define a role to map for each of row, column and value.
* For example, assume that you have a custom QAbstractItemModel for storing various monthly values
* related to a business.
* Each item in the model has roles "year", "month", "income", and "expenses".
* You could do the following to display the data in a bar chart:
*
* \snippet doc_src_qtdatavis3d.cpp 3
