Your current version of "chart-myTest.php" is missing the enhancements I
said you should make above. Replace the javascript in that file with this:
function drawChart() {
var jsonData = $.ajax({
url: "data-file.php",
dataType:"json",
async: false
}).responseText;
var data = new google.visualization.DataTable(JSON.parse(jsonData));
var chart = new
google.visualization.PieChart(document.getElementById('chart_div'));
chart.draw(data, {
// put the chart options in here
height: 800,
width: 800
});
}
google.load('visualization', '1', {'packages':['corechart'], callback:
drawChart});
