title: visual analogue scale psychopy
body: <p>I'm developing a metacognition experiment in PsychoPy (v. 1.90.1) and I need a visual analogue scale to measure confidence. However, I can't find a way to remove the numeric values (<code>0</code> and <code>1</code>) from the extremities of the Psychopy VAS. 
  Is there any way to hide them? </p>
  
  <p>I need the word labels (<code>"Not at all confident"</code>, <code>"Extremely confident"</code>) but I would also like to have the answers recorded on a <code>0-100</code> scale (or an equivalent <code>0-1</code>) as the analogue scale does (so switching to categorical wouldn't do).</p>
  
  <p>Any suggestion?</p>
  
  <p>Thanks in advance.</p>
  
  <p>Sonia</p>
