这是我第一次使用Highcharts,我正在努力解决一个小问题,这个问题不能让我在工作中走得更远。
我在MySQL中有一个数据库,我试图使用Highcharts在图表上显示一些信息。
问题在于,即使经过多次尝试,我仍然无法展示我的系列,我无法理解为什么。
这是我的代码:
data.php
<?php
try
{
$bdd = new PDO('mysql:host=localhost;dbname=name', 'root', '');
}
catch (Exception $e)
{
die('Erreur : ' . $e->getMessage());
}
$sql=<<<SQL
SELECT DATE, Traf_BH_TCH_Erl, Trafic_HR_BH, Block_BH_TCH
FROM 182_d_all
WHERE BCF='TIMNAY'
SQL;
$reponse = $bdd->query($sql);
$bln = array();
$rows = array();
$bln['name'] = 'Date';
$rows['name'] = 'Traf_BH_TCH_Erl';
while($donnee=$reponse->fetch()){
$bln['data'][] = $donnee['DATE'];
$rows['data'][] = $donnee['Traf_BH_TCH_Erl'];
}
$rslt = array();
array_push($rslt, $bln);
array_push($rslt, $rows);
print json_encode($rslt, JSON_NUMERIC_CHECK);
$reponse->closeCursor();
?>
line.php
<?php
$cakeDescription = "Highcharts Pie Chart";
?>

};
$.getJSON("data.php", function(json) {

options.series[0] = json[1];
chart = new Highcharts.Chart(options);
});
});

<div id="container" style="min-width: 400px; height: 400px; margin: 0 auto"></div>
</body>
</html>
问题是该系列的所有值都等于零。 我不明白为什么它全部空白而不是显示价值?
感谢您的回答!

JSON看起来像:
[{&#34; name&#34;:&#34; Date&#34;,&#34; data&#34;:[&#34; \ n5 / 6/2015 00:00:00&#34 ;,&#34; \ n17 / 6/2015 00:00:0&#34;,&#34; \ n15 / 6/2015 00:00:0&#34;,&#34; \ n11 / 6/2015 00:00:0&#34;,&#34; \ n11 / 6/2015 00:00:0&#34;,&#34;

这里有很多事情......
我为了从您的数据中获取功能示例而进行了一些更改:
您必须创建一个&#39;数据&#39;内部字段&#39;系列&#39;:
series: [{
data: []
}]
您必须设置&#39;数据&#39;来自&#39;系列[0]&#39;的属性并从您的JSON传递数据字段:
options.series[0].data = text[1].data;
您必须使用数字作为y坐标数据,因此您应使用点作为小数分隔符,不要使用引号:
{"name":"Traf_BH_TCH_Erl","data":[11.23,3.36,4.08,11.96,9.97]}
您没有正确使用具有日期格式的X轴,但您可以在第一个Highcharts工作后搜索该轴。 ;)
