在配置中加入这行代码

	plotOptions: {
		series: {
			borderWidth: 0,
			dataLabels: {
				enabled: true,
				format: '{point.y:.1f}%'
			}
		}

可以将小的数据显示在柱状图上

Highcharts.chart('container', {
	chart: {
		type: 'column'
	},
	title: {
		text: '2015年1月-5月，各浏览器的市场份额'
	},
	subtitle: {
		text: '点击可查看具体的版本数据，数据来源: <a href="https://netmarketshare.com">netmarketshare.com</a>.'
	},
	xAxis: {
		type: 'category'
	},
	yAxis: {
		title: {
			text: '总的市场份额'
		}
	},
	legend: {
		enabled: false
	},
	plotOptions: {
		series: {
			borderWidth: 0,
			dataLabels: {
				enabled: true,
				format: '{point.y:.1f}%'
			}
		}
	},
	tooltip: {
		headerFormat: '<span style="font-size:11px">{series.name}</span><br>',
		pointFormat: '<span style="color:{point.color}">{point.name}</span>: <b>{point.y:.2f}%</b> of total<br/>'
