Adjust the baseline circle segment for round scales. 
<p>
The baseline will be drawn from min(angle1,angle2) to max(angle1, angle2). The default setting is [ -135, 135 ]. An angle of 0 degrees corresponds to the 12 o'clock position, and positive angles count in a clockwise direction. <dl compact><dt><b>Parameters:</b></dt><dd>

<li>
The angle range is limited to [-360, 360] degrees. Angles exceeding this range will be clipped. </li>

If you need a counterclockwise scale, use QwtScaleDiv::setRange </li>
