Highcharts add several series with PHP array -

-

i'm using highcharts display database informations, when use 1 series haven't problems, when want add several series on chart, it's little bit difficult.

first php script :

foreach ($informationslier $keyfille => $fille) {     $grafdata = array();      foreach ($fille['information'] $keyinfos => $information) {         $mois = $information['created']->format('m');         $mois = $mois - 1;          $timestamp = strtotime($information['created']->format('j').'-'.$mois.'-'.$information['created']->format('y'));         //multiply 1000 seconds in js         $timestamp = $timestamp * 1000;         $grafdata[$keyinfos] = array($timestamp, (float)$information['valeur']);         //$grafdata[$keyinfos] = implode(', ', $grafdata[$keyinfos]);         //$grafdata[] = "[date.utc(".$information['created']->format('y').','.$mois.','.$information['created']->format('j')."),".$information['valeur']."]";     }      $tabinformationsdata[$keyfille]['name'] = 'evolution '.$fille['titre'];     $tabinformationsdata[$keyfille]['color'] = '#ffa020';     //$tabinformationsdata['infos'][$keyfille]['data'] = array();      //$implodegraf = implode(',', $grafdata);     $tabinformationsdata[$keyfille]['data'] = $grafdata; }

the php script return me :

array (      [0] => array          (             [name] => evolution pourcentage             [color] => #ffa020             [data] => array                 (                     [0] => array                         (                             [0] => 1451084400000                             [1] => 17.00                         )                     [1] => array                         (                             [0] => 1451170800000                             [1] => 19.00                         )                     [2] => array                         (                             [0] => 1451257200000                             [1] => 14.00                         )                     [3] => array                         (                             [0] => 1451343600000                             [1] => 6.00                         )                 )         ) )

i send array view , :

series: {{ graphique | json_encode() | raw }},

but in html, rendering looks , doesn't work :

series: [{     "name":"evolution pourcentage",     "color":"#ffa020",     "data":[[1451084400000,"17.00"],[1451170800000,"19.00"],[1451257200000,"14.00"],[1451343600000,"6.00"]] }],

i don't know why doesn't work... try multiply 1000 timestamp or not nothing work. so, how can display series ?

work passing date timestamp , adding (float) before values... edited post response.
