我尝试使用 php 和 highcharts api 打印存储在我的数据库中的结果。但是图表没有显示在屏幕上。甚至没有显示轴。数据是从 mysql 数据库获取的。我尝试使用与在 highcharts 演示中，但没有运气。
这是我的代码
<?php
require_once ('connection.php');
session_start();
$username = $_SESSION['username'];
$quizes=null;
$score=array();
$i=0;
$result = mysql_query("SELECT * FROM `score` WHERE `username`='$username'") or die(mysql_error);
while($rows=mysql_fetch_array($result)) {
$quizes= $quizes. "'".$rows['quiz']."',";
$score[$i]=$rows['score'];
$i=$i+1;
}
print_r($score);
echo $quizes;
?>
<html>
<body>
<script src="js/jquery.js"></script>
<script src="highcharts/js/highcharts.js"></script>
<script type="text/javascript">
$(document).ready(function() {
//passing php variables to javascript variables
//eg var mk1=<?php echo $mark1 ?>;
var mk1=<?php echo $score[1] ?>;
var mk2=<?php echo $score[2] ?>;
var mk3=<?php echo $score[3] ?>;
var mk4=<?php echo $score[4] ?>;
var mk5=<?php echo $score[5] ?>;
var mk6=<?php echo $score[6] ?>;
var mk7=<?php echo $score[7] ?>;
var mk8=<?php echo $score[8] ?>;
var chart1 = new Highcharts.Chart({
chart: {
renderTo: 'graphDiv',
defaultSeriesType: 'column'
},
title: {
text: 'SEMESTER'
},
xAxis: {
categories: ['QUIZ A', 'QUIZ B', 'QUIZ C', 'QUIZ D', 'QUIZ E', 'QUIZ F','QUIZ G','QUIZ H']
},
yAxis: {
title: {
text: 'Percentage'
}
},
series: [{
name: ['Quiz Progress'],
data: [mk1, mk2, mk3, mk4, mk5, mk6, mk7, mk8]
},]
});
});
</script>
<div id="graphDiv" style="width: 700px; height: 400px; float: left"></div>
</body>
</html>
最佳答案
这里是从 highchart 中的 mysql 数据库获取数据的示例。 以免开始于 Index.php
<head>
<meta name="Gopal Joshi" content="Highchart with Mysql" />
<meta http-equiv="content-type" content="text/html; charset=utf-8" />
<title>Highchart with Mysql Database</title>
<script type="text/javascript" src="js/jquery.min.js"></script>
<script type="text/javascript" src="js/setup.js"></script>
<script type="text/javascript" src="js/test.js"></script>
</head>
<body>
<script src="js/highcharts.js"></script>
<div id="sales" style="min-width: 310px; height: 400px; margin: 0 auto"></div>
</body>
setup.js
var chart;
$(document).ready(function() {
var cursan = {
chart: {
renderTo: 'sales',
defaultSeriesType: 'area',
marginRight: 10,
marginBottom: 20
},
title: {
text: 'Highchart With Mysql',
},
subtitle: {
text: 'www.spjoshis.blogspot.com',
},
xAxis: {
categories: ['Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec', 'Jan', 'Feb', 'Mar']
},
yAxis: {
title: {
text: 'Average'
},
plotLines: [{
value: 0,
width: 1,
color: '#808080'
}]
},
tooltip: {
crosshairs: true,
shared: true
},
legend: {
layout: 'vertical',
align: 'right',
verticalAlign: 'top',
x: -10,
y: 30,
borderWidth: 0
},
plotOptions: {
series: {
cursor: 'pointer',
marker: {
lineWidth: 1
}
}
},
series: [{
color: Highcharts.getOptions().colors[2],
name: 'Test Colomn',
marker: {
fillColor: '#FFFFFF',
lineWidth: 3,
lineColor: null // inherit from series
},
dataLabels: {
enabled: true,
rotation: 0,
color: '#666666',
align: 'top',
x: -10,
y: -10,
style: {
fontSize: '9px',
fontFamily: 'Verdana, sans-serif',
textShadow: '0 0 0px black'
}
}
}],
}
//Fetch MySql Records
jQuery.get('js/data.php', null, function(tsv) {
var lines = [];
traffic = [];
try {
// split the data return into lines and parse them
tsv = tsv.split(/\n/g);
jQuery.each(tsv, function(i, line) {
line = line.split(/\t/);
date = line[0] ;
amo=parseFloat(line[1].replace(',', ''));
if (isNaN(amo)) {
amo = null;
}
traffic.push([
date,
amo
]);
});
} catch (e) { }
cursan.series[0].data = traffic;
chart = new Highcharts.Chart(cursan);
});
});
这里js将使用data.php文件从mysql导入数据并将其提供给我们的图表
data.php
$con=mysql_connect('localhost','root','');
mysql_select_db("test", $con);
$result=mysql_query('select * from sales order by id');
while($row = mysql_fetch_array($result)) {
echo $row['month'] . "\t" . $row['amount']. "\n";
}
data.php 将简单地在页面上打印我们将用于图表的值。
您可以将此方法用于同一页面上的多个图表，并且多个图表不再需要更多文件。
它将输出类似
