title: Real-time Java graph / chart library?
body: <p>There was an earlier thread on <a href="https://stackoverflow.com/questions/527640/java-graph-or-chart-library">Java graph or chart library</a>, where JFreeChart was found to be quite good, <strong>but</strong>, as <a href="http://www.jfree.org/jfreechart/faq.html#FAQ5" rel="nofollow noreferrer">stated in its FAQ</a>, it's not meant for real-time rendering.</p>
  
  <p>Can anyone recommend a comparable library that supports real-time rendering? Just some basic xy-rendering - for instance, getting a voltage signal from data acquisition system and plotting it as it comes (time on x-axis, voltage on y-axis).</p>
