title: How do rotate x-axis labels to left or negative in c3.js?
body: <p>How do you rotate x-axis labels to left or negative using c3js.org?  <a href="http://c3js.org/samples/axes_x_tick_rotate.html" rel="nofollow noreferrer">This example</a> gives the following code:</p>
  
  <pre><code>axis: {
      x: {
          type: 'category',
          tick: {
              rotate: 75,
              multiline: false
          },
          height: 130
      }
  }
  </code></pre>
  
  <p>But if I try "<strong>rotate: -65,</strong>" instead like <a href="https://bl.ocks.org/d3noob/3c040800ff6457717cca586ae9547dbf" rel="nofollow noreferrer">this d3js.org example</a>, the x-axis labels disappear from the plot.  I am using "type: 'timeseries',", but I don't think that makes a difference.</p>
