我想知道如何显示饼图的图例，我目前做了一列饼图向下钻取，但饼图没有图例，我想知道如何放置它？我尝试将 Legend = true 设置为 true 但它仍然没有显示在饼图中。
我也试过：
pie: { allowPointSelect: true, cursor: 'pointer', dataLabels: { enabled: false }, showInLegend: true }
我的代码如下：
Highcharts.chart('container', {
chart: {
type: 'column'
},
title: {
text: 'Chart showing the total vs match dialogs'
},
xAxis: {
type: 'category'
},
yAxis: {
title: {
text: ''
}
},
legend: {
enabled: false
},
plotOptions: {
series: {
borderWidth: 0,
dataLabels: {
enabled: true,
formatter: function () {
var mychart = $('#container').highcharts();
var mytotal = 0;
for (i = 0; i < mychart.series.length; i++) {
if (mychart.series[i].visible) {
mytotal = {!! $countTotalRecord['low confidence'] !!} + {!! $countTotalRecord['no answer'] !!} + {!! $countTotalRecord['missing intent'] !!} + {!! $countTotalRecord['webhook fail'] !!};
}
}
var pcnt = (this.y / mytotal) * 100;
return Highcharts.numberFormat(pcnt) + '%';
}
}
}
},
tooltip: {
// headerFormat: '<span style="font-size:11px">{series.name}</span><br>',
pointFormat: '{point.name}: <b>{point.y}</b>'
},
credits:{
enabled:false
},
series: [{
name: 'front',
colorByPoint: true,
data: [{
name: 'Total',
y: {!! $countTotalRecord['total'] !!},
drilldown: 'total'
}, {
name: 'Match',
y: {!! $countTotalRecord['match'] !!},
drilldown: 'match'
}]
}],
drilldown: {
series: [{
name: 'total',
id: 'total',
type:'pie',
data: [
[
'Low Confidence',
{!! $countTotalRecord['low confidence'] !!}
],
[
'No Answer',
{!! $countTotalRecord['no answer'] !!}
],
[
'Missing Intent',
{!! $countTotalRecord['missing intent'] !!}
],
[
'Webhook Fail',
{!! $countTotalRecord['webhook fail'] !!}
]
]
}]
}
});你必须使用
events: {
drilldown: function(e) {
this.options.legend["enabled"] = true; //legend shows
},
drillup: function(e) {
this.options.legend["enabled"] = false; //legend hides
},
}
// Create the chart
Highcharts.chart('container', {
chart: {
type: 'column',
events: {
drilldown: function(e) {
this.options.legend["enabled"] = true;
},
drillup: function(e) {
this.options.legend["enabled"] = false;
},
}
},
