title: Overflowing X axis (ggplot2)
body: <p>I have a list of companies that includes three variables: year founded, market capitalization and company name (actually, ticker symbol). </p>
  
  <p>I want to plot them by year founded (X axis) and market capitalization (Y axis) with fill determined by vendor name. </p>
  
  <p>Doing this:</p>
  
  <pre><code> qplot(factor(Founded), Market.Cap, data = mcap, geom = "bar", fill = Vendor)
  </code></pre>
  
  <p>Gets me that, but the X-axis is illegible (see below). I've tried to feed scale_x_discrete() values (1900 - 2012, etc) but had no luck. How do I tell ggplot2 not to display the actual values but instead a spectrum of my choosing? </p>
  
  <p>And as a side note, if you can remind me how to avoid the scientific notation on the Y-axis, great. </p>
