Fix point label drawing for XYSeries...
Fix point label drawing for XYSeries Reverting change 810e912b2c05d5f4305b0f1e56be57e765a30479. m_points is used for the point label because that has the series point information. The points variable that is passed to the function is used for positioning the label as it has the coordinates.

\class QVXYModelMapper
\inmodule Qt Charts
\brief Vertical model mapper for QXYSeries.
\mainclass
Model mappers allow you to use QAbstractItemModel derived models as a data source for a chart series.
Vertical model mapper is used to create a connection between QXYSeries and QAbstractItemModel derived model object.
It is possible to use both QAbstractItemModel and QXYSeries model API. QXYModelMapper makes sure that QXYSeries and the model are kept in sync.
Note: used model has to support adding/removing rows/columns and modifying the data of the cells.

\brief Vertical model mapper for QXYSeries.
VXYModelMapper allows you to use your own QAbstractItemModel derived model with data in columns

XYSeries data API to manipulate data. VXYModelMapper keeps the series and the model in sync.
