如何隐藏图表导出的按钮，我只需要导出JPEG，PDF，SVG其他的都不需要
$(function () {
var chart = Highcharts.chart('container', {
title: {
text: '外部调用导出'
},
credits: {
enabled: false
},
xAxis: {
categories: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec']
},
exporting: {
buttons:{
contextButton:{
menuItems:[
{
text:'下载PDF文件',
onClick:function(){
chart.exportChart({
type:'application/pdf',
filename: 'my-pdf'
})
}
}
]
}
},
// enabled: true,
chartOptions: { // specific options for the exported image
plotOptions: {
series: {
dataLabels: {
enabled: true
}
}
}
},
},
series: [{
data: [29.9, 71.5, 106.4, 129.2, 144.0, 176.0, 135.6, 148.5, 216.4, 194.1, 95.6, 54.4]
}],
});
});
这是我的代码，为什么click执行后没有执行导出方法
注意大小写，onClick 应该是 onclick
感谢回复。
我自定义了节点卡片，并且使用了客户端导出，但是导出的文件不显示头像图片是为什么？如果用官方的导出服务器会正常显示头像
