title: Set minimum step size in chart js
body: <p>I am using <a href="http://www.chartjs.org" rel="noreferrer">Chart.js</a> 2.0 version to draw graphs, i want to define <strong>minimum step size</strong> in bar graph</p>
  <pre><code>var myNewChart = new Chart(grapharea, {
                  type: 'bar',
                  data: barData,
                  options: {
                      responsive: true,                        
                      scales: {
                          yAxes: [
                              {
                                  ticks: {
                                      min: 0, // it is for ignoring negative step.
                                      beginAtZero: true,
                                      stepSize: 1  // if i use this it always set it '1', which look very awkward if it have high value  e.g. '100'.
                                  }
                              }
                          ]
                      }
                  }
              });
  </code></pre>
  <p>this time i am using</p>
  <blockquote>
  <p>stepSize: 1</p>
  </blockquote>
  <p>i am using this step size to <strong>ignore the point value e.g. '0.5'</strong>, it shows when the max graph values id less e.g '2'.<br />
  if i use this it always set the step it '1', which look very awkward if it have high value  e.g. '100'.</p>
  <blockquote>
  <p>I am looking for such thing:
  suggestedMin = 1</p>
  </blockquote>
  <p>Is there any thing to define thie minimum step size which should not be fixed in higher value cases.</p>
