title: flot bar chart ticks not displaying
body: <p>my data:</p>
  
  <pre><code>var data5 = [
      { label: "my cat",  data: [[1,10], [4,20], [7,30]], color: 'rgb(85, 96, 42)'},
      { label: "my job",  data: [[2,30], [5,20], [8,30]], color: '#42215F'}
  ];
  </code></pre>
  
  <p>my options:</p>
  
  <pre><code>var type = {};
  type[charttype] = {show: true};
  type["xaxis"] = {ticks: [[1,"foo"], [2,"bar"], [4,"cat"], [5,"woo"], [7,"cookie"], [8,"yay"]]};
  
  var chart_options = {};
  chart_options["series"] = type;
  </code></pre>
  
  <p>however, when I </p>
  
  <pre><code>var plot = $.plot($(div), data5, chart_options);
  </code></pre>
  
  <p>The ticks just show up as 1-9, instead of with the strings I've given.
  What am I doing wrong?</p>
