title: Google Charts Date axis labels not correct
body: <p>I have been working on Google Line charts having a date axis. I have noticed that the axis labels ticks are determined by the number of gridlines and are not same to the data that I am passing. Could someone please tell me how I could force the axis labels to be in sync with the data I am passing.
  Please find the link for the fiddle: <a href="https://jsfiddle.net/FarhanI/5ga6xu44/" rel="nofollow">https://jsfiddle.net/FarhanI/5ga6xu44/</a></p>
  
  <pre><code>  function drawChart() {
  
      var data = new google.visualization.DataTable();
      data.addColumn('date', 'Time of Day');
      data.addColumn('number', 'Rating');
  
      data.addRows([
        [new Date(2015, 0, 1), 5],
        [new Date(2015, 0, 7), 3],[new Date(2015, 0, 14), 3], [new Date(2015, 0, 21), 2],[new Date(2015, 0, 28), 8],
      ]);
  
  
      var options = {
        title: 'Rate the Day on a Scale of 1 to 10',
        width: 900,
        height: 500,
        hAxis: {
          format: 'M/d/yy',
          gridlines: {count: 9}
        },
        vAxis: {
          gridlines: {color: 'none'},
  
        }
      };
  
      var chart = new google.visualization.LineChart(document.getElementById('chart_div'));
  
      chart.draw(data, options);
  
      var button = document.getElementById('change');
  
      button.onclick = function () {
  
        // If the format option matches, change it to the new option,
        // if not, reset it to the original format.
        options.hAxis.format === 'M/d/yy' ?
        options.hAxis.format = 'MMM dd, yyyy' :
        options.hAxis.format = 'M/d/yy';
  
        chart.draw(data, options);
      };
    }

  <p>Also I am trying to have the gridline appear as the y axis since I was unable to get the Y axis with line charts. I tried specifying gridline as 1, but I was able to get only 1 gridline that too in the middle of the X axis.</p>
  
  <p>Could someone please let me know if I could get Y axis with the line chart.</p>
  
  <p>Appreciate the assistance,
  Farhan.</p>
