title: jQuery flot chart threshold
body: <p>I see that the flotchart threshold <a href="http://www.flotcharts.org/flot/examples/threshold/index.html" rel="nofollow">add-in</a> allows me to chart using a line style with points as shown in this <a href="http://jsfiddle.net/ringstaff/frEPW/" rel="nofollow">jsfiddle</a>.</p>
  
  <p>Notice that when you toggle the points attribute from false to true, there are points that show up when the line crosses the x-axis at zero.  For my scenario, I only want to display points that correspond to an actual data value, not when the line happens to intersect with the x-axis.</p>
  
  <pre><code>points: { show: true }
  </code></pre>
  
  <p>I read through as much as I could find online on this add-in, but can't seem to find the right parameters to configure.  Any pointers are appreciated.</p>
