! Adds a new axis to the axis rect side specified with \a type, and returns it. If \a axis is 0, a new QCPAxis instance is created internally. QCustomPlot owns the returned axis, so if you want to remove an axis, use \ref removeAxis instead of deleting it manually. You may inject QCPAxis instances (or subclasses of QCPAxis) by setting \a axis to an axis that was previously created outsi
