我允許多個選擇,同時點擊(第一次點擊選擇一個圖表,第二次點擊在該圖表上執行鑽取)。我想要顯示一個顯示所有選定圖表的工具提示(或者任何其他方式)(即:如果我選擇兩個圖表,我希望工具提示顯示關於這兩個圖表的信息)。Highcharts的工具提示顯示選定的點
這裏我的HTML:

<body>
<div id="container" style="min-width: 310px; height: 400px; margin: 0 auto"></div>
<!-- <button id="button">Get selected points</button>
<div>event: <span id="label"></span></div>-->
</body>
</html>
在這裏,我的JavaScript文件:
$(function() {
// Create the chart
$('#container').highcharts({
chart: {
type: 'column',
events: {
drilldown: function (e) {
if (!e.seriesOptions && e.point.selected) {
var chart = this,
points = chart.getSelectedPoints(),
drilldowns = {
'Animals': {
name: 'Animals',
data: [
['Cows', 2],
['Sheep', 3]
]
},
'Fruits': {
name: 'Fruits',
data: [
['Apples', 5],
['Oranges', 7],
['Bananas', 2]
]
},
'Cars': {
name: 'Cars',
data: [
['Toyota', 1],
['Volkswagen', 2],
['Opel', 5]
]
}
};
Highcharts.each(points, function (p) {
chart.addSingleSeriesAsDrilldown(p, drilldowns[p.name]);
});
chart.applyDrilldown();
}
},
drillup: function (e) {
var chart = this,
points = [];
setTimeout(function() {
points = chart.getSelectedPoints();
Highcharts.each(points, function (p) {
// unselect points from previous drilldown
p.selected = false;
p.setState('', true);
});
}, 0);
}
}
},
title: {
text: 'Async drilldown'
},
xAxis: {
type: 'category',
categories: [
'Animals',
'Fruits',
'Cars'
],
},
yAxis: {
title: {
text: 'Values'
}
},
tooltip: {
headerFormat: '<span style="font-size:10px">{point.key}</span><table>',
pointFormat: '<tr><td style="color:{series.color};padding:0">{series.name}: </td>' +
'<td style="padding:0"><b>{point.y:.1f}</b></td></tr>',
footerFormat: '</table>',
shared: false,
useHTML: true
},
legend: {
enabled: false
},
plotOptions: {
column: {
allowPointSelect: true
},
series: {
borderWidth: 0,
dataLabels: {
enabled: true
}
}
},
series: [{
allowPointSelect: true,
name: 'Test things',
colorByPoint: true,
data: [{
name: 'Animals',
y: 5,
drilldown: true
}, {
name: 'Fruits',
y: 2,
drilldown: true
}, {
name: 'Cars',
y: 4,
drilldown: true
}]
}],
drilldown: {
series: []
}
});
});
編輯:我試過這個解決方案,但unfortunetely只顯示所選擇的最後一點:
plotOptions: {
column: {
allowPointSelect: true
},
series: {
borderWidth: 0,
dataLabels: {
enabled: true
},
point: {
events: {
select: function() {
var text = this.category + ': ' + this.y + ' was last selected',
chart = this.series.chart;
if (!chart.lbl) {
chart.lbl = chart.renderer.label(text, 100, 70)
.attr({
padding: 10,
r: 5,
fill: Highcharts.getOptions().colors[1],
zIndex: 5
})
.css({
color: '#FFFFFF'
})
.add();
} else {
chart.lbl.attr({
text: text
});
}
}
}
},
}
},
感謝您的幫助!
這應該是一個評論,因爲在的jsfiddle你的例子是完全一樣的作爲我的,你不會把代碼來幫助我的問題。無論如何,感謝您訪問 –
@FranranBuireu代碼已更改,請參閱編輯以查看描述不夠清楚的部分。 –
我已經修改了一些代碼,以確保在鑽取時X軸顯示當前系列的值(在動物船和牛或其他)。這是我的錯,因爲我在最後一分鐘改變了它,但你的代碼工作正常。接受的答案:) –
