title: Flot With "String" x-axis
body: <p>When using flot I would like to have a string based x-axis. For example I have a list of customers "Bob", "Chris", "Joe" and would like to plot their revenue on the Y-Axis. (this is a bar graph)</p>
  
  <p>It seems at first glance flot only supports numeric types on the x-axis. Is this true?</p>
