    <script type="text/javascript">
      google.charts.load('current', {'packages':['bar']});

      function drawChart() {
        var data = google.visualization.arrayToDataTable([

     var options = {
          chart: {
            title: 'Google_Chart_Test',
            subtitle: 'Bar graph test',
           var chart = new google.charts.Bar(document.getElementById('columnchart_material'));
