-

the result of query use display 3 column (country, date, items). php code side

 $res = db_query($sql); $dat = array();  while($r = db_fetch_array($res)){     $dat[]= array($r['date'], $r['items'], $r['country']); }  // armar $start_date = ''; if(count($dat)>0){     $s = split(' ',$dat[0][0]);     $ss = split('-',$s[0]); } // cada objeto en $dats es una grafica $dats[] = array('type'=>'line',             'name'=>$q['title'],             'pointinterval'=>24 * 3600 * 1000,             'pointstart'=>mktime(0,0,0,$ss[1],$ss[2],$ss[0])*1000,             'data'=>$dat) ; //echo "$sql"; echo json_encode($dats,json_numeric_check);

my javascript code :

function loadline(_data){     $('#line_container').highcharts({         chart: {zoomtype: 'x',spacingright: 20},         title: { text: 'monthly created items'},         subtitle: {text:'updated every day'},         xaxis: {             type: 'datetime',             maxzoom: 7 * 24 * 3600000, // fourteen days             title: {text: null}         },         yaxis: {title: {text: 'created items'}},         tooltip: {shared: true},         legend: {enabled: true},         plotoptions: {             area: {                 fillcolor: {                     lineargradient: { x1: 0, y1: 0, x2: 0, y2: 1},                     stops: [                         [0, highcharts.getoptions().colors[0]],                         [1, highcharts.color(highcharts.getoptions().colors[0]).setopacity(0).get('rgba')]                     ]                 },                 linewidth: 1,                 marker: {                     enabled: false                 },                 shadow: false,                 states: {                     hover: {                         linewidth: 1                     }                 },                 threshold: null             }         },         series: _data     }); }

how change "series 1" in graph country name receive in query? data have in query has date until "april" (ytd) graph shows months in future, how correct this? if have more 1 country in query how display in multiple chart lines @ same time. in advance.

you have supplied single series, translate single line. try like: 

 $res = db_query($sql); $dat = array();  while($r = db_fetch_array($res)){     if (!isset($dat[$r['country']]))         $dat[$r['country']] = [];      $dat[$r['country']][] = array($r['date'], $r['items'], $r['country']); }  // armar $start_date = ''; if(count($dat)>0){     $s = split(' ',$dat[0][0]);     $ss = split('-',$s[0]); } // cada objeto en $dats es una grafica $dats = []; foreach ($dat $country => $values) { $dats[] = array('type'=>'line',             'name'=>$q['title'],             'pointinterval'=>24 * 3600 * 1000,             'pointstart'=>mktime(0,0,0,$ss[1],$ss[2],$ss[0])*1000,             'data'=>$values) ; } //echo "$sql"; echo json_encode($dats,json_numeric_check);
