There is an issue that I cannot solve, I\'ve been looking a lot in the internet but found nothing.
I have this JavaScript that is used to do an Ajax request by PHP.
Could you provide a sample of the data returned ? You may call directly drawData(html) :
$.ajax({
type: "POST",
async: false,
url: "getTIER1Tickets.php",
data: "",
success: function(html){
// Succesful, load visualization API and send data
google.load('visualization', '1', {'packages': ['annotatedtimeline']});
//You are already in a callback function, better like this ?
drawData(html);
}});
