You are not required to draw the chart on page load, you just have to make
sure that it doesn't start until after the API has finished loading. You
can do this with AJAX requests as long as you are loading something other
than the API with the AJAX. Here's a rough workup you could use (uses
jQuery's AJAX function to fetch a json representation of a DataTable from a
php script and draw a chart):
google.load('visualization', '1', {packages: ['corechart']});
google.setOnLoadCallback(init);
function init () {
$.ajax({
url: 'path/to/data.php',
type: 'json',
success: function (json) {
// do something with json
// the draw the chart here, maybe:
var data = new google.visualization.DataTable(json);
var chart = new google.visualization.LineChart(document.
getElementById('myChart'));
chart.draw(data, {
title: 'My Chart'
});
}
});
}
