yAxis: {
    min: 0,
    title: {
        text: 'Total fruit consumption'
    },
    stackLabels: {
        enabled: false,
        style: {
            fontWeight: 'bold',
            color: (Highcharts.theme && Highcharts.theme.textColor) || 'gray'
        }
    }
},
您需要像上面的示例一样将 stackLabels 设置为 false
stackLabels: {
            enabled: true,
