我正在使用Highcharts JavaScript庫來可視化一些浮點值,我通過php提供給js代碼。如下圖所示,每個點的鼠標懸停現在都會顯示與軸值和文本「text:undefined」對應的兩個值。 如何在Highcharts Javascript庫的散點圖點上添加額外的標籤?
我的問題是:有沒有顯示散點圖的每個點不同的文本的方法嗎?我有一個對應於每個點的文本,但我沒有找到顯示它的方法。
我的JavaScript/PHP的代碼是:
<script type="text/javascript">
$(function() {
var chart;
$(document).ready(function() {
chart = new Highcharts.Chart({
chart: {
renderTo: 'container',
type: 'scatter',
zoomType: 'xy'},
title: {
text: 'Average 24hrs Sentiment for <?php echo $channel?> by Gender '
},
subtitle: {
text: 'Source: '
},
xAxis: {
title: {
enabled: true,
text: 'Hours ([0-24h].[0-60mins])'
},
startOnTick: true,
endOnTick: true,
showLastLabel: true
},
yAxis: {
title: {
text: 'Sentiment (N. Bayes) %'
}
},
tooltip: {
formatter: function() {
return ''+
this.x +' hrs, '+ this.y +' sentiment, text: ';
}
},
legend: {
layout: 'vertical',
align: 'left',
verticalAlign: 'top',
x: 24,
y: 1,
floating: true,
backgroundColor: '#FFFFFF',
borderWidth: 1
},
plotOptions: {
scatter: {
marker: {
radius: 5,
states: {
hover: {
enabled: true,
lineColor: 'rgb(100,100,100)'
}
}
},
states: {
hover: {
marker: {
enabled: false
}
}
}
}
},
series: [{
name: 'Female',
color: 'rgba(223, 83, 83, .5)',
data: [
<?php
for($j=0;$j<$i1;$j++)
{
if($females[$j]['Hour'][0] == "0")
{
echo '['.$females[$j]['Hour'][1].'.'.$females[$j]['Min'].','.$females[$j]['Sent'].'"]';
}
else
echo '['.$females[$j]['Hour'].'.'.$females[$j]['Min'].','.$females[$j]['Sent'].'"]';
if(($j+1)!=$i1)
{
echo ",";
}
}
?>
]},
{
name: 'Male',
color: 'rgba(119, 152, 191, .5)',
data: [
<?php
for($j=0;$j<$i2;$j++)
{
if($males[$j]['Hour'][0] == "0")
{
echo '['.$males[$j]['Hour'][1].'.'.$males[$j]['Min'].','.$males[$j]['Sent'].',"'.$males[$j]['Text'].'"]';
}
else
echo '['.$males[$j]['Hour'].'.'.$males[$j]['Min'].','.$males[$j]['Sent'].',"'.$males[$j]['Text'].'"]';
if(($j+1)!=$i2)
{
echo ",";
}
}
?>
]}]
});
});
});
謝謝。
來做到這一點你的例子真的很有幫助,我設法做到了我的可視化。謝謝。 – 2012-08-09 17:31:51
更改了簡化樣本: tooltip:{pointFormat:'locked:{point.locked}
unlocked:{point.unlocked}
potential:{point.potential}'} – 2013-06-17 20:40:15
