title: Is ZedGraph library development still active? If not - are there any open source replacements?
body: <p>I'm about to start working on a new .NET project where I'm going to need to put real-time data from a hardware device on a chart and I was surprised to find out that <a href="http://zedgraph.org/wiki/index.php?title=Revision_History" rel="nofollow noreferrer">ZedGraph development seems to have died out</a> (last activity on the wiki is noted in late 2007). Is that true?</p>
  
  <p>If so, are there any good open-source replacements for ZedGraph for .NET? Or should I roll my own? I'm considering the Microsoft charting toolkit but I'm concerned that - as with the the other commercial solutions out there - I may hit a road block if I'm going to need any non-standard features (of which there may be a few).</p>
  
  <p>I should add that I've used ZedGraph in the past and that my experience was pretty good with it.</p>
