* \brief Base series class for Q3DSurface.

*
* QSurface3DSeries manages the series specific visual elements, as well as series data
* (via data proxy).
*
* If no data proxy is set explicitly for the series, QSurface3DSeries creates a default
* proxy. If any other proxy is set as active data proxy later, the default proxy and all data
* added to it are destroyed.
*
* QSurface3DSeries supports the following format tags for QAbstract3DSeries::setItemLabelFormat():
* \table
* \row
* \li @xTitle \li Title from X axis
* \row
* \li @yTitle \li Title from Y axis
* \row
* \li @zTitle \li Title from Z axis
* \row
* \li @xLabel \li Item value formatted using the same format as the X axis attached to the graph uses,
* see \l{Q3DValueAxis::setLabelFormat()} for more information.
* \row
* \li @yLabel \li Item value formatted using the same format as the Y axis attached to the graph uses,
* see \l{Q3DValueAxis::setLabelFormat()} for more information.
* \row
* \li @zLabel \li Item value formatted using the same format as the Z axis attached to the graph uses,
