将图表导出为 PNG 时,我正在尝试在饼图上添加图例。这是我的代码:
var chart_23_106;
$(document).ready(function () {
chart_23_106 = new Highcharts.Chart({
chart: { type: 'pie', renderTo: 'container_23_106', plotBackgroundColor: null, plotBorderWidth: null, plotShadow: false },
title: { text: 'NRJ' },
tooltip: { pointFormat: '{series.name}: <b>{point.percentage}%</b>', percentageDecimals: 1 },
plotOptions: {
pie: { borderWidth: 0, shadow: false, allowPointSelect: true, cursor: 'pointer', dataLabels: { enabled: false } }
},
colors: ['#9F9F9F','#BE6EBE','#FFA74F','#B7B7D0','#CBE22A','#00C8C8'],
credits: { enabled: false, text: "Source: Air Normand", href: "" },
exporting:{ buttons: {
printButton: {enabled:false},
exportButton: {menuItems:null,onclick:function(){this.exportChart(null,
{ chart: {reflow: false, width: 400},
title: {text: "Répartition de la Consommation"},
subtitle: {text: "Haute-Normandie"},
plotOptions: {pie: {dataLabels: {enabled: true}, showInLegend: true}},
credits: {enabled: true} }
);}}
}},
lang: {exportButtonTitle: "Export image au format PNG"},
series: [{
type: 'pie',
name: 'Proportion',
data: [
['Activite 1', 684.6],
['Activite 2', 564.7],
['Activite 3', 244.4],
['Activite 4', 42.8],
]
}]
});
});
在函数 exportChart 中,除了 plotOptions 之外的所有函数都给出了正确的效果。在PNG文件中,更改了标题,添加了副标题和学分,但没有出现dataLabels和图例......
有人知道为什么吗?
谁能帮助我?谢谢
