Highcharts与负面堆栈栏:如何显示左右不同的工具提示
问题描述:
我正在使用负面堆栈的highcharts栏,问题是当我将鼠标悬停在红色的图表左侧时,显示正确的疾病名称这是“TB可疑”,但是当我将鼠标悬停在蓝条就显示了同样的“TB可疑病”这是错误的,它应该显示“中耳炎” 同样的问题对于所有其他疾病Highcharts与负面堆栈栏:如何显示左右不同的工具提示
这里是代码
<script>
$(function() {
if($('#disease-bar').length > 0){
// Age categories
var categories_c = [<?=$comm_disease_title?$comm_disease_title:0;?>];
var categories_nc = [<?=$non_comm_disease_title?$non_comm_disease_title:0;?>];
$(document).ready(function() {
$('#disease-bar').highcharts({

var s = Math.abs(this.value);

这里是我使用
tooltip: {{
formatter: function() {
return '<b>' + this.point.category + '</b><br/>' +
'Diseases: <b>' + Math.abs(this.point.y) +'</b>';
}
},

我能得到从格式正确的类别:
formatter: function() {
var subCategoryLabel = this.series.chart.xAxis[this.series._i]
.categories[this.point.index];
return '<b>' + subCategoryLabel + '</b><br/>' +
'Diseases: <b>' + Math.abs(this.point.y) + '</b>';
}
答
您必须修改序列数据作为对象,其中dd
是各自的类别名和y
的阵列是值
series: [{
name: 'Communicable',
data: [{y:-1489599,dd:'Acute (Upper) Respiratory Infections'}, {y:-256548,dd:'Scabies'}, {y:-157531,dd:'Diarrhoea/Dysentery < 5 yrs'}, {y:-148696,dd:'Diarrhoea/Dysentery > 5 yrs'}, {y:-86283,dd:'Worm Infestations'}]
//url: 'disease.php?frequency=m&year=2017&month=1&quarter=&fatype=&disease_cat=comm'
}, {
name: 'Non-communicable',
data: [{y:399786,dd:'Fever due to other causes'}, {y:247500,dd:'Peptic Ulcer Diseases'}, {y:196653,dd:'Hypertension'}, {y:176866,dd:'Dental Caries'}, {y:169514,dd:'Diabetes Mellitus'}]
//url: 'disease.php?frequency=m&year=2017&month=1&quarter=&fatype=&disease_cat=noncomm'
}]
在你的提示,您可以通过传递的“点”的对象属性访问
tooltip: {
formatter: function() {
return '<b>' + this.point.dd + '</b><br/>' +
'Diseases: <b>' + Math.abs(this.point.y) + '</b>';
}
},
