title: HTML5 Oscilloscope
body: <p>I need a free real-time chart (preferably HTML5) which can plot incoming signals like an oscilloscope. I found two examples which are very close to what I want:</p>
  
  <ul>
  <li><a href="http://flotcharts.org/" rel="nofollow">http://flotcharts.org/</a></li>
  <li><a href="http://smoothiecharts.org/" rel="nofollow">http://smoothiecharts.org/</a></li>
  </ul>
  
  <p>Both can display incoming data in real-time, but they scroll the data from right to left, and I try to accomplish exactly the opposite: draw new data from left to right, and when at the end of the page, overwrite the previous data in a sweep (like most oscilloscopes). If the chart can do both modes, sweeping and scrolling, that's even better. But all components I found untill now support only the lather.</p>
  
  <p>Here is a video of the kind of display I'm after: <a href="http://www.youtube.com/watch?v=chZqN605Iz4" rel="nofollow">http://www.youtube.com/watch?v=chZqN605Iz4</a></p>
