Get image from Google API Chart

by

once the 'ready' has fired on the chart,
you can use getImageURI to get a base 64 string,
which can be saved as .PNG,
or included in an img tag,
as in the following example…

to use a frozen version, you can replace 'current' with the latest save — '45'

google.charts.load('current', {
  callback: function () {
    var data = new google.visualization.DataTable();
    data.addColumn('date', 'Date');
    data.addColumn('number', '2005');
    data.addColumn('number', '2006');
    data.addRows([
       [new Date('01/01/2016'), 200, 210],
       [new Date('01/02/2016'), 190, 220],
       [new Date('01/03/2016'), 205, 200],
       [new Date('01/04/2016'), 220, 230],
       [new Date('01/05/2016'), 212, 210],
       [new Date('01/06/2016'), 185, 193],
       [new Date('01/07/2016'), 196, 207]
    ]);
    var options = {
      height: 400
    };

    var chart = new google.visualization.LineChart(document.getElementById('chart_div'));

    google.visualization.events.addListener(chart, 'ready', function () {
      document.getElementById('image_div').innerHTML = '<img alt="Chart" src="' + chart.getImageURI() + '">';
    });

    chart.draw(data, options);
  },
  packages: ['corechart']
});
