Hi,
I want  to display a chart where one Set of values is used plotting left Y-axis and the other set of values is marked on the right-hand Y-axis.
Attaching a mockup. Could someone suggest how to plot it.

This the code am trying for the required mockup. 
<html>
  <head>
    <script type="text/javascript" src="https://www.gstatic.com/charts/loader.js"></script>
    <script type="text/javascript">
      google.charts.load('current', {'packages':['corechart']});
      google.charts.setOnLoadCallback(drawStuff);

      function drawStuff() {
        var data = new google.visualization.arrayToDataTable([
          ['Galaxy', 'Distance', 'Brightness'],
          ['Canis Major Dwarf', 8000, 23.3],
          ['Sagittarius Dwarf', 24000, 4.5],
          ['Ursa Major II Dwarf', 30000, 14.3],
          ['Lg. Magellanic Cloud', 50000, 0.9],
          ['Bootes I', 60000, 13.1]
        ]);

        var options = {
          width: 900,
          chart: {
            title: 'Nearby galaxies',
            subtitle: 'distance on the left, brightness on the right'
          },
  
          series: {
            0: { type : 'bars' , axis: 'distance' }, // Bind series 0 to an axis named 'distance'.
            1: { type: 'line',axis: 'brightness'  } // Bind series 1 to an axis named 'brightness'.
          },
          axes: {
            y: {
              distance: {label: 'parsecs'}, // Left y-axis.
              brightness: {side: 'right', label: 'apparent magnitude'} // Right y-axis.
            }
          }
        };

      var chart = new google.visualization.ComboChart(document.getElementById('dual_y_div'));
      chart.draw(data, options);
    };
    </script>
  </head>
  <body>
    <div id="dual_y_div" style="width: 900px; height: 500px;"></div>
  </body>
</html>

Hi Neha,

You are mixing the classic chart with the material chart options.  The material chart doesn't support combining bars and lines, so you will have to stick with the classic charts and specify the left of right sides with the series 'targetAxisIndex' option.

        series: {
          0: {targetAxisIndex: 0, type: 'bars'},
          1: {targetAxisIndex: 1, type: 'line'}
        },
