title: What superseded XYGraph.dll?
body: <p>I am trying to get some charting and visualizations going in F#. Unfortunately, the book I am using refers to a lot of .dll files that have been superseded with the advent of Windows 7. I am using Visual Studio 2010, F# 2.0.</p>
  
  <p>What would be a useful replacement for "XYGraph.dll" for doing some simple graphs of mathematical functions?</p>
  
  <p>Searching MSDN does not yield any results.</p>
