title: Given quartiles, how do I draw a box-whisker using MATLAB, matplotlib, gnuplot, or some other package?
body: <p>I'm given a number of data points like this:</p>
  
  <pre class="lang-none prettyprint-override"><code>2.50%   3.45
  25.00%  4.19
  50.00%  4.7
  75.00%  5.42
  97.50%  6.87
  </code></pre>
  
  <p>This defines a complete box-whisker element for a plot. I'm not sure how I can plot this. All the methods I've looked up so far (<a href="http://www.mathworks.com/help/stats/boxplot.html" rel="noreferrer">MATLAB</a>, <a href="http://matplotlib.org/api/pyplot_api.html#matplotlib.pyplot.boxplot" rel="noreferrer">matplotlib</a>, <a href="http://www.gnuplot.info/demo_canvas/boxplot.html" rel="noreferrer">gnuplot</a>) construct boxes from the original data. I don't have access to the original data, but I do have all the information I <em>should</em> need to draw the boxes.</p>
  
  <p>What's the best way to draw the boxes/whiskers without the data?</p>
