Change the label flags. 
<p>
Labels are aligned to the point ticklength + spacing away from the backbone.<p>
The alignment is relative to the orientation of the label text. In case of an flags of 0 the label will be aligned depending on the orientation of the scale:<p>
QwtScaleDraw::TopScale: Qt::AlignHCenter | Qt::AlignTop<br>
 QwtScaleDraw::BottomScale: Qt::AlignHCenter | Qt::AlignBottom<br>
 QwtScaleDraw::LeftScale: Qt::AlignLeft | Qt::AlignVCenter<br>
 QwtScaleDraw::RightScale: Qt::AlignRight | Qt::AlignVCenter<br>
<p>
Changing the alignment is often necessary for rotated labels.<p>
