You are not using mysql_query correctly. You need to fetch results from
the query and output the results to your DataTable.
$row = mysql_fetch_assoc($yes);
$countYes = $row['YesOrNo'];
$row = mysql_fetch_assoc($no);
$countNo = $row['YesOrNo'];
//...
var data = google.visualization.arrayToDataTable([
['YesOrNo', 'Mount'],
['Yes', <?php echo $countYes; ?>],
['No', <?php echo $countNo; ?>]
]);
Also, if you are fetching data from a single table, you don't need to use
two separate queries, you can combine them into one (the structure of the
query depends on how your table is laid out, I can help you figure it out
if you want).
