几天来,我一直在通过 php 与 highcharts 和 json_encode 搏斗。我相信我的数据格式正确,但图表没有正确更新。类别数据已更新,用于绘制列和行数据的系列数据已按应有的格式格式化。
谁能帮我完成剩下的工作。这是我正在使用的 php 脚本和 highcharts javascript。
谢谢您的帮助:
<?php
// data feed to power dynamic charts
include_once('db_conn.php');
// get site data and store in array
$query = mysql_query("SELECT site, SUM(impressions) AS impressions, SUM(clicks) AS clicks FROM dfa_data WHERE campaign='$campaign' and time='$time' GROUP BY site ORDER BY impressions DESC");
$rows = array();
while($r = mysql_fetch_array($query)) {
$rows['categories'][] = $r['site'];
}
// get impression data and store in array
$query = mysql_query("SELECT site, SUM(impressions) AS impressions, SUM(clicks) AS clicks FROM dfa_data WHERE campaign='$campaign' and time='$time' GROUP BY site ORDER BY impressions DESC");
$rows1 = array();
$rows1['name'] = 'Impressions';
$rows1['color'] = '#4572A7';
$rows1['type'] = 'column';
$rows1['yAxis'] = 1;
while($rr = mysql_fetch_array($query)) {
$rows1['data'][] = $rr['impressions'];
}
// get ctr data and store in array
$query = mysql_query("SELECT site, SUM(impressions) AS impressions, SUM(clicks) AS clicks FROM dfa_data WHERE campaign='$campaign' and time='$time' GROUP BY site ORDER BY impressions DESC");
$rows2 = array();
$rows2['name'] = 'CTR';
$rows2['color'] = '#89A54E';
$rows2['type'] = 'spline';
while($rrr = mysql_fetch_array($query)) {
$ctr = number_format(($rrr['clicks']/$rrr['impressions'])*(100),2,'.',',');
$impressions = number_format($rrr['impressions'],0,'.',',');
$clicks = number_format($rrr['clicks'],0,'.',',');
$rows2['data'][] = $ctr;
}
$result = array();
$result1 = array();
array_push($result,$rows);
array_push($result1,$rows1);
array_push($result1,$rows2);
?>
<script>
$(function () {
$('#container').highcharts({
chart: {
zoomType: 'xy'
},
title: {
text: 'Performance by Site'
},
subtitle: {
text: ''
},
xAxis:
<?php echo json_encode($result); ?>
,
yAxis: [{ // Primary yAxis
labels: {
format: '{value}%',
style: {
color: '#89A54E'
}
},
title: {
text: 'CTR',
style: {
color: '#89A54E'
}
}
}, { // Secondary yAxis
title: {
text: 'Impressions',
style: {
color: '#4572A7'
}
},
labels: {
format: '{value}',
style: {
color: '#4572A7'
}
},
opposite: true
}],
tooltip: {
shared: true
},
series: <?php echo json_encode($result1); ?>
});
});
</script>
var_dump($result) 输出以下内容
array(1) { [0]=> array(1) { ["categories"]=> array(5) { [0]=> string(13) "Search Medica" [1]=> string(10) "Medscape 4" [2]=> string(11) "onclive.com" [3]=> string(22) "Oncology Nurse Advisor" [4]=> string(25) "chemotherapyadvisor.com 1" } } }
var_dump($result1) 输出以下内容
string(7) "result1"
以下是两者的 json_encode 输出:
json_encode $结果
[{"categories":["Search Medica","Medscape 4","onclive.com","Oncology Nurse Advisor","chemotherapyadvisor.com 1"]}]
json_encode $result1
[{"name":"Impressions","color":"#4572A7","type":"column","yAxis":1,"data":[140521,71905,69295,68456,49487]},{"name":"CTR","color":"#89A54E","type":"spline","data":[0.11,0.04,0.2,0.09,0.05]}]
