QChart mapping functions: return QPoint(0, 0) if series type is Pie...
QChart mapping functions: return QPoint(0, 0) if series type is Pie Some QLogValueAxis tests added. Most commented out. LogDomain correctly move, zoomin and zoomout when log base is less than 1

HBarModelMapper allows you to use your own QAbstractItemModel derived model with data in rows as a data source
Tero Ahola
QML model mapper documentation for pie and xy
 r1516 for any bar series. It is possible to use both QAbstractItemModel and bar series data API to manipulate data.
HBarModelMapper keeps the series and the model in sync.
The following QML example would create a bar series with three bar sets (assuming the model has
at least four rows). Each bar set would contain data starting from column 1. The name of a set would be defined by
the vertical header (of the row).
