我想在我的图表中添加一个范围选择器，但我不知道该怎么做。 我已经尝试了一些来自 JSFIDDLE 的例子，但它不起作用。
这是我的代码：
<meta http-equiv="refresh" content="65;url=http://localhost/23-1_chart.php"/>
<title>XXX</title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
<link rel="stylesheet" href="css/XXX.css">
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.8.2/jquery.min.js" type="text/javascript"></script>
<script src="http://code.highcharts.com/highcharts.js"></script>
<script src="http://code.highcharts.com/modules/exporting.js"></script>
<script type="text/javascript" src="data.js" ></script>
</head>
<body>
<div id="chart" style="height: 400px; margin: 0 auto"></div>
<script>
$(function() {
//Highcharts with mySQL and PHP - Ajax101.com
var Voc_value = [];
var time = [];
var switch1 = true;
$.get('23-1_values.php', function(data) {
data = data.split('/');
for (var i in data) {
if (switch1 == true) {
time.push(data[i]);
switch1 = false;
} else {
Voc_value.push(parseFloat(data[i]));
switch1 = true;
}
}
time.pop(); // cursor
$('#chart').highcharts({
chart : {
type : 'spline'
},
title : {
text : 'VOC-Value-A.ROOM'
},
subtitle : {
text : 'Room A'
},
xAxis : {
title : {
text : 'time'
},
categories : time
},
yAxis : {
title : {
text : 'VOC-value in ppm'
},
labels : {
formatter : function() {
return this.value + 'VOCvalue'
}
}
},
tooltip : {
crosshairs : true,
shared : true,
valueSuffix : 'ppm'
},
plotOptions : {
spline : {
marker : {
radius : 4,
lineColor : '#666666',
lineWidth : 1
}
}
},
series : [{
name : 'VOC-value in ppm',
data : Voc_value
}]
});
});
});</script>
首先，我读取 sql 值并将其放入 23-1_values.php。我的 sql 值是从这个 php 页面23.1_values.php读取的，然后构建图表。我在横坐标轴上有日期时间（日-小时-分钟-s），在纵坐标轴上有 ppm 值我得到的值太多，想减少日期格式并在图表中添加范围选择器。
我该怎么做？
谢谢
我真的不知道我做了什么，但它现在正在工作。非常感谢你帮助我。这是代码：
