高潮点不在正确的位置

Question

我正在制作一个包含Highcharts的折线图，并从mysql中检索数据。这是我的代码：

<?php 

     $query = "select distinct idchip from datatable ";
     $result = mysql_query( $query );
     $rows = array();
     $count = 0;

     while( $row = mysql_fetch_array( $result ) ) {

         $table = array();

         $query2 = "select datetime,temperature from datatable where idchip=".$row['idchip'].' ';
         $query3 = "select datetime from datatable where idchip=".$row['idchip'].' group by datetime ASC';
         $timeresult = mysql_query($query3);

            while($datatime  = mysql_fetch_array($timeresult))
            {
                $newtime .= $datatime['0'].',';


                $newcates .= "'".$datatime['0']."',";
            } 

            $total= explode(",", $newtime);
            array_pop($total);
            $count = 0;

            $dataresult = mysql_query($query2);
            while($datarow = mysql_fetch_array($dataresult))
            {

                $data = '';
                //$datatimes = '';

                $datatimes .= $datarow['0'].',';

                //$stringtime .= $datatimes;


                $timetotal = explode(",",$datatimes);

                array_pop($timetotal);
                echo count($total).' |';

                //echo count($timetotal).' |';
                //echo $timetotal[$count]." |";
                $data .= (integer)$datarow['1'].',';
                $stringdata .= $data;

                }

        $newstring = $stringdata ;
        //$total = '';
        //$newtime = '';
        $stringdata = '';
        $stringtime = '';

        //$stringcates = '';
        //echo $newstring;
        $namedata = "{name:'Chip ".$row["idchip"]."',data:[$newstring]},";
        $getall .= $namedata;

     }

     $serries = 'series: [ '.$getall.' ]';
     $xAxis = 'xAxis: { categories:['.$newcates.']},';


?>

这就是我希望它在图表上显示，芯片7的节点数据必须在“它必须在这里”位置：

所以你们看到数据不正确点，因为数据阵列不在它的位置。所以现在我需要在$ newstring中添加一些“null”，这样我就会有这个字符串：null，null，[我的数据显示] - ＆gt;这些空节点将帮助我将数据放在正确的位置。但我尽我所能，无法得到帮助我做到这一点，请帮助我。我希望在YAxis的时间与XAxis不同时为字符串添加一些'null'，这样数据点就能正确显示。

这是我的数据库：

                id  idchip  datetime       signal temperature
