31
A class for drawing scales.
33
<a class="el" href="class_qwt_scale_draw.html">QwtScaleDraw</a> can be used to draw linear or logarithmic scales. A scale has a position, an alignment and a length, which can be specified . The labels can be rotated and aligned to the ticks using <a class="el" href="class_qwt_scale_draw.html#bf5881339fddde65a00c1dd391023320">setLabelRotation()</a> and <a class="el" href="class_qwt_scale_draw.html#3df0a1fe4a498ef028a5348e54bfaa7f">setLabelAlignment()</a>.<p>
34
After a scale division has been specified as a <a class="el" href="class_qwt_scale_div.html">QwtScaleDiv</a> object using <a class="el" href="class_qwt_abstract_scale_draw.html#4399aac94a294f5ed6c52114dde00d2f">QwtAbstractScaleDraw::setScaleDiv(const QwtScaleDiv &s)</a>, the scale can be drawn with the <a class="el" href="class_qwt_abstract_scale_draw.html#c4442d7480db1288971e7eac15142467">QwtAbstractScaleDraw::draw()</a> member.

Change the label flags.
624
Labels are aligned to the point ticklength + spacing away from the backbone.<p>
625
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>
626
QwtScaleDraw::TopScale: Qt::AlignHCenter | Qt::AlignTop<br>
627
QwtScaleDraw::BottomScale: Qt::AlignHCenter | Qt::AlignBottom<br>
