Draw multiple Google charts in for loop

Question

I am trying to draw multiple Google charts in a for loop, but can\'t seem to make it work. I have seen some similar questions being asked, but only with PHP. Anyone who can

Answer 1

setOnLoadCallback should only be called once per page load

once it fires, you can draw as many charts as needed

you can also include the callback in the load statement

see following working snippet...

google.charts.load('current', {
  callback: function () {
    var data = new google.visualization.DataTable();
    data.addColumn('string', 'Topping');
    data.addColumn('number', 'Slices');
    data.addRows([
      ['Mushrooms', 1],
      ['Onions', 1],
      ['Olives', 2],
      ['Zucchini', 2],
      ['Pepperoni', 1]
    ]);
    var options = {
      title:'How Much Pizza Sarah Ate Last Night',
      width:400,
      height:300
    };

    for (var i = 0; i < 6; i++) {
      var container = document.getElementById('draw-charts').appendChild(document.createElement('div'));
      var chart = new google.visualization.PieChart(container);
      chart.draw(data, options);
    }
  },
  packages: ['corechart']
});
