我有一个简单的问题,但由于某种原因找不到解决方案。如此处所述:highcharts 文档,我制作了以下脚本:
<script type="text/javascript">
$(document).ready(function() {
var options = {
chart: {
renderTo: 'container',
type: 'column',
},
title: {
text: 'Dagelijks waterverbruik'
},
subtitle: {
text: 'Waterverbruik in liters'
},
xAxis: {
categories: [
'Zondag',
'Maanag',
'Dinsdag',
'Woensdag',
'Donderdag',
'Vrijdag',
'Zaterdag'
]
},
yAxis: {
min: 0,
title: {
text: 'Waterverbruik (Liter)'
}
},
plotOptions: {
column: {
pointPadding: 0.2,
borderWidth: 0
}
},
series: [{}]
};
$.getJSON('testdata.php', function(data) {
options.series[0].data = data;
var chart = new Highcharts.Chart(options);
});
});
</script>
我的 testdata.php 如下:
<?php
header('Content-Type: application/json');
$data[] = array('Zondag',11);
$data[] = array('Maandag',10);
$data[] = array('Dinsdag',9);
$data[] = array('Woensdag',8);
$data[] = array('Donderdag',12);
$data[] = array('Vrijdag',2);
$data[] = array('Zaterdag',18);
$serie1[] = array('name' => 'serie 1', 'data' => $data);
$serie1[] = array('name' => 'serie 2', 'data' => $data);
echo json_encode($serie1);
?>
由于某种原因,图表不呈现。我究竟做错了什么?一个系列以这种方式工作,但多个系列却没有。
如您所见,我希望两个条具有相同的值。testdata.php 的输出是:
[{"name":"serie 1","data":[["Zondag",11],["Maandag",10],["Dinsdag",9],["Woensdag",8],["Donderdag",12],["Vrijdag",2],["Zaterdag",18]]},{"name":"serie 2","data":[["Zondag",11],["Maandag",10],["Dinsdag",9],["Woensdag",8],["Donderdag",12],["Vrijdag",2],["Zaterdag",18]]}]
