var data = new google.visualization.DataTable();
data.addColumn('string', 'list');
data.addColumn('number', 'Tutorials Pesentage');
data.addRows(5);
data.setValue(0, 0, 'jQuery');
data.setValue(0, 1, 11);
data.setValue(1, 0, 'Java');

Please tell me How I can load the data From
MySQL in PHP & use the Google Visualization API to draw chart Dynamically.

to use this Dynamically try this

$i = 1;
$userinfo = mysql_query("SELECT * FROM users");
while($order = mysql_fetch_array($orders)) {
$username = $userinfo[username];
$sales = $userinfo[sales];

$arr[$i] = array("username" => $username, "sales" => $sales );
}

// now all the usernames are stored in the array to output this to the chart do this.

data.setValue(0, 0, $arr[1][username]);
data.setValue(0, 1, $arr[1][sales]);

hope this will help you
