title: Create horizontal reference line in matlab
body: <p>I tried to create  a horizontal reference line using refline</p>
  
  <pre><code> hline = refline(0,0.);
      set(hline,'color','r');
      set(hline,'Marker','o');
      set(hline,'LineStyle','-');
  </code></pre>
  
  <p>This generates the desired refline except that the marker 'O' is set at the start point and end point only.
  how can I have the entile horizontal refline to have the 'o'  marker?Am I missing something here.?</p>
