title: Change Y-axis in Google chart?
body: <p>This is the code which I tried to show the chart with the help of Google chart.</p>
  
  <pre><code>&lt;script type="text/javascript" src="https://www.gstatic.com/charts/loader.js"&gt;&lt;/script&gt;
         &lt;div id="chart_div"&gt;&lt;/div&gt;
      &lt;br/&gt;
  
      &lt;script&gt;
          google.charts.load('current', {'packages':['bar']});
  
        google.charts.setOnLoadCallback(drawChart);
        function drawChart() {
          var data = google.visualization.arrayToDataTable([
            ['Year', 'Sales', 'Expenses', 'Profit'],
            ['2014', 1000, 400, 200],
            ['2015', 1170, 460, 250],
            ['2016', 660, 1120, 300],
            ['2017', 1030, 540, 350]
          ]);
  
          var options = {
            chart: {
              title: 'Company Performance',
              subtitle: 'Sales, Expenses, and Profit: 2014-2017',
            },
            bars: 'Vertical', // Required for Material Bar Charts.
            hAxis: {format: 'decimal'},
            height: 400,
            colors: ['#1b9e77', '#d95f02', '#7570b3']
          };
  
          var chart = new google.charts.Bar(document.getElementById('chart_div'));
  
          chart.draw(data, google.charts.Bar.convertOptions(options));
  
          var btns = document.getElementById('btn-group');
  
          btns.onclick = function (e) {
  
            if (e.target.tagName === 'BUTTON') {
              options.hAxis.format = e.target.id === 'none' ? '' : e.target.id;
              chart.draw(data, google.charts.Bar.convertOptions(options));
            }
          }
        }
        &lt;/script&gt;
