Everything about google column chart

column chart is a graphical representation of data. Where column chart displays data as vertical bars. Here we are showing a simple example of column chart with the help of Google API.

The below column chart represents the company performance in the last five years. Representing years on the x-axis and performance count on the y-axis.

Here is the sample code

<html>
  <head>
    <script type="text/javascript" src="https://www.gstatic.com/charts/loader.js"></script>
    <script type="text/javascript">
      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],
          ['2018', 1000, 500, 300]
        ]);

        var options = {
          chart: {
            title: 'Company Performance',
            subtitle: 'Sales, Expenses, and Profit: 2014-2017',
          }
        };

        var chart = new google.charts.Bar(document.getElementById('columnchart_material'));

        chart.draw(data, google.charts.Bar.convertOptions(options));
      }
    </script>
  </head>
  <body>
    <div id="columnchart_material" style="width: 800px; height: 500px;"></div>
  </body>
</html>
