++ * \class QBarDataProxy

++ * \ingroup graphs_3D
++ * \brief The QBarDataProxy class is the data proxy for a 3D bars graph.
++ *
++ * A bar data proxy handles adding, inserting, changing, and removing rows of
++ * data.
++ *
++ * The data array is a list of vectors (rows) of QBarDataItem instances.
++ * Each row can contain a different number of items or even be null.
++ *
++ * QBarDataProxy takes ownership of all QtGraphs::QBarDataRow objects
++ * passed to it, whether directly or in a QtGraphs::QBarDataArray container.
++ * If bar data row pointers are used to directly modify data after adding the
++ * array to the proxy, the appropriate signal must be emitted to update the
++ * graph.
++ *
++ * QBarDataProxy optionally keeps track of row and column labels, which
++ * QCategory3DAxis can utilize to show axis labels.
++ *
++ * The row and column labels are stored in a separate array from the data in the
++ * series rather. Row processing methods are available in the proxy and provide
++ * alternative versions that do not affect row labels. This enables
++ * the option of having row labels that relate to the position of the data in
++ * the array rather than the data itself. Since the series holds the data and
++ * row and column labels, it is necessary to create a series associated with the
++ * proxy before using these functions for them.
