title: How to plot 3 dimensional array?
body: <p>I have three dimensional array of data that is generated from web server logs for my cloud application. The data consists of a weekly count from each server's log for a particular request (e.g., GET /login.php or POST /update.php).</p>
  
  <p>The header of the first dimension contains the server names. <br>
  The header of the second dimension contains the request types. <br>
  The header of the third dimension contains the particular weeks. <br>
  The data is just a number (the count).</p>
  
  <p>E.g., for three servers, for two request types, and for two weeks,</p>
  
  <pre><code>SERVER REQUEST WEEK COUNT
       1       1    1  1234
       1       1    2  5678
       1       2    1  9012
       1       2    2  3456
       2       1    1  7890
       2       1    2  1234
       2       2    1  5678
       2       2    2  9012
       3       1    1  3456
       3       1    2  7890
       3       2    1  1234
       3       2    2  5678
  </code></pre>
  
  <p>What are some programs/libraries that will graph this data (e.g., in bar charts spread out over a surface)?</p>
  
  <p>Is there a file format that will easily allow to use this data for multiple programs/libraries?</p>
  
  <p>OS/language does not matter.</p>
