    \class QAbstractAxis
    \inmodule Qt Charts
    \brief The QAbstractAxis class is used for manipulating chart's axis.

    Each series can be bound to one or more horizontal and vertical axes, but mixing axis types
    that would result in different domains is not supported, such as specifying
    QValueAxis and QLogValueAxis on the same orientation.

    Properties and visibility of various axis elements such as axis line, title, labels, grid lines,
    and shades can be individually controlled.
