所以基本上我需要在悬停时显示堆叠列的标签,但我还需要显示我正在悬停的那一列的上一列和下一列的标签。
总结一下,如果我有A,B,C,D和E(每个有3个堆叠的列),我将鼠标悬停在C上,我应该可以看到B,C和D的标签(对于所有3个堆叠的标签)列)(和工具提示仅适用于C,但这是默认值,所以不需要帮助)。
知道如何实现这个目标吗?
这是通用代码:
Highcharts.chart('container', {
chart: {
type: 'column'
},
title: {
text: 'Stacked column chart'
},
xAxis: {
categories: ['Apples', 'Oranges', 'Pears', 'Grapes', 'Bananas']
},
yAxis: {
min: 0,
title: {
text: 'Total fruit consumption'
},
stackLabels: {
enabled: true,
style: {
fontWeight: 'bold',
color: (Highcharts.theme && Highcharts.theme.textColor) || 'gray'
}
}
},
legend: {
align: 'right',
x: -30,
verticalAlign: 'top',
y: 25,
floating: true,
backgroundColor: (Highcharts.theme && Highcharts.theme.background2) || 'white',
borderColor: '#CCC',
borderWidth: 1,
shadow: false
},
tooltip: {
headerFormat: '<b>{point.x}</b><br/>',
pointFormat: '{series.name}: {point.y}<br/>Total: {point.stackTotal}'
},
plotOptions: {
column: {
stacking: 'normal',
dataLabels: {
enabled: true,
color: (Highcharts.theme && Highcharts.theme.dataLabelsColor) || 'white'
}
}
},
series: [{
name: 'John',
data: [5, 3, 4, 7, 2]
}, {
name: 'Jane',
data: [2, 2, 3, 2, 1]
}, {
name: 'Joe',
data: [3, 4, 4, 2, 5]
}]
});
这是一个jfiddle,其中包含通用堆叠列设置。

您可以使用CSS和Highcharts事件隐藏/显示标签,演示:http://jsfiddle.net/2549acmt/
默认CSS:
.highcharts-stack-labels text {
visibility: hidden;
}
和JS事件:
function showLabels() {
var index = this.x,
labels = document.querySelectorAll(".highcharts-stack-labels text");
// previous
if (index > 0) {
labels[index - 1].style.visibility = 'visible';
}
// current
labels[index].style.visibility = 'visible';
// next
if (labels[index + 1]) {
labels[index + 1].style.visibility = 'visible';
}
}
function hideLabels() {
var index = this.x,
labels = document.querySelectorAll(".highcharts-stack-labels text");
if (index > 0) {
labels[index - 1].style.visibility = 'hidden';
}
labels[index].style.visibility = 'hidden';
if (labels[index + 1]) {
labels[index + 1].style.visibility = 'hidden';
}
}
附加事件:
plotOptions: {
column: {
stacking: 'normal',
dataLabels: {
enabled: true,
color: (Highcharts.theme && Highcharts.theme.dataLabelsColor) || 'white'
},
point: {
events: {
mouseOver: showLabels,
mouseOut: hideLabels
}
}
}
},
