title: Google Chart: How to draw the vertical axis for LineChart?
body: <p>I want to draw a Google's line chart in my web page! Here is my js code:</p>
  
  <pre><code>function drawVisualization() {
    // Create and populate the data table.
    var data = google.visualization.arrayToDataTable([
      ['x', 'Cats', 'Blanket 1'],
      ['A',   1,       10],
      ['B',   2,       5],
      ['C',   4,       12],
      ['D',   8,       5]
    ]);
  
    var options = {
        curveType: 'function',
        lineWidth: 2,
        hAxis: {
          baselineColor: 'red', 
          textStyle: {color: '#000', fontName: 'Arial', fontSize: 10}, 
          gridlines: { color: '#f3f3f3', count: 5} 
        },
        vAxis: {
          baseline: 0, 
          viewWindowMode: "explicit", 
          viewWindow:{ min: 0 },
          gridlines: { color: '#f3f3f3', count: 6} 
        }
      };
    new google.visualization.LineChart(document.getElementById('visualization')).
        draw(data, options);
  }
  </code></pre>
  
  <p>However, the result chart is drawing without any vertical axis line. How I can add the vertical axis lines as below images:
