You're not charting 3 series there, you have 1 series. Looking at your SQL
table, I would guess that you want to display one series for each sample
id, right? If so, then you need to break out the "prodPerct" column into 3
different columns - 1 for each series. This is probably best achieved in
SQL, maybe with a query like this:
SELECT
PsiBar,
SUM(IF(id_sample = 1, prodPerct, null)) AS prodPerct1,
SUM(IF(id_sample = 2, prodPerct, null)) AS prodPerct2,
SUM(IF(id_sample = 3, prodPerct, null)) AS prodPerct3
FROM tbl_dilution
GROUP BY PsiBar
and then use this to build the table:
$table['cols'] = array(
array('label' => 'PsiBar', 'type' => 'number'),
array('label' => 'Series 1', 'type' => 'number')
array('label' => 'Series 2', 'type' => 'number')
array('label' => 'Series 3', 'type' => 'number')
);
$rows = array();
while($r = mysql_fetch_assoc($sth)) {
$temp = array();
$temp[] = array('v' => (float) $r['psiBar']);
$temp[] = array('v' => (float) $r['prodPerct1']);
$temp[] = array('v' => (float) $r['prodPerct2']);
$temp[] = array('v' => (float) $r['prodPerct3']);
$rows[] = array('c' => $temp);
}
