@jerry_k7,
dataPoints can accept [{"x": 1, "y": 23},...]
or labels and few other properties like indexLabel, color, etc and not as id and temp. Changing $point = array("id" => $row['id'] , "temp" => $row['temp']);
to $point = array("x" => $row['id'] , "y" => $row['temp']);
in data.php should work fine in your case. Please download the updated sample code here.
