如何在echarts中的每个水平条的顶部放置标签？

var myChart = echarts.init(document.getElementById('chart'));

var data = [
    {value: 335, name: '数据1'},
    {value: 310, name: '数据2'},
    {value: 234, name: '数据3'},
    {value: 135, name: '数据4'},
    {value: 1548, name: '数据5'}
];

series: [
    {
        type: 'bar',
        data: data,
        label: {
            show: true,
            position: 'top'
        }
    }
]

myChart.setOption({
    series: [
        {
            type: 'bar',
            data: data,
            label: {
                show: true,
                position: 'top'
            }
        }
    ]
});
