title: Ticks attribute not working in chartist.js
body: <p>Here's some simple code with two charts: <a href="https://jsfiddle.net/g4sqzseo/3/" rel="nofollow">JSFiddle</a>
  The ticks attribute works fine with the line chart but does not with the bar chart. Interestingly it works fine when posted on Chartist website (in examples section). But I really need to have it working in my .js file.</p>
  
  <pre><code>new Chartist.Bar(
      '#barChart', 
      {
          labels: ['Week 1', 'Week 2', 'Week 3', 'Week 4', 'Week 5'],
          series: [
              {name: 'one', data: [5, 6, 8, 9, 5]},
              {name: 'two', data: [4, 5, 6, 5, 4]},
              {name: 'three', data: [2, 4, 5, 2, 1]}
          ]
      },
      {
          width: 565,
          height: 200,
          axisY: {
              type: Chartist.FixedScaleAxis,  
              low: 0,
              high: 10,
              ticks: [0, 5, 10]                // the ticks don't show up 
          }
      }
  );
  </code></pre>
