Hi... i follow your instruction here, but it didn't work...
focus on this:
foreach ($results as $row) {
echo "data.addRow(['{$row['foo']}', {$row['bar']}]);";
}
So, if u have 3 or more rows, you will have:
data.addRow(['{$row['foo']}', {$row['bar']}]);data.addRow(['{$row['foo']}',
{$row['bar']}]);data.addRow(['{$row['foo']}', {$row['bar']}]);
well, that will not work.
