title: Google Chart : Remove repetitive y axis
body: <p>I am using google chart which is working absolutely fine except one thing the issue is when I select custom date filter and choose only single date from it then it will show only 1 record with little dot which is also fine no issue with that but its y axis shows repetitive values in it.</p>
  
  <p>Please check example : 
  <a href="http://awesomescreenshot.com/0f757w8k3a" rel="nofollow">http://awesomescreenshot.com/0f757w8k3a</a></p>
  
  <p>it shows 0, 1, 1, 2, 2
  it should show 0, 1, 2, 3, 4 or just 0, 1, 2</p>
  
  <pre><code>var options = {
                  vAxis: {
                      format: '#',
                      minValue: 0,
                      gridlines: {
                          color: 'transparent'
                      },
                      viewWindowMode: "explicit",
                      viewWindow:{ min: 0 }
                  },
                  hAxis: { textPosition: 'none' },
                  legend: { position: 'none' },
                  colors:[{color:'#A8D1FF', darker:'#97B9D8'}]
              };
  
              var chart = new google.visualization.AreaChart(document.getElementById('PostChart'));
              chart.draw(PostChartData, options);
  </code></pre>
