Question

我在Highchart的帮助下开发图表，但数据标签显示不正确。在每个栏上我想写“你好，你好，你好2等”在条形图上，但目前显示的是Y轴值。

检查js fiddle http://jsfiddle.net/NM2Cp/251/

js代码是

var count = 0;
var options = {
    exporting: {
        url: 'http://export.highcharts.com/'
    },
    chart: {
        type: 'column'
    },
    title: {
        text: 'Monthly Average Rainfall'
    },
    legend:{
        enabled:false
    },
    subtitle: {
        text: 'Source: WorldClimate.com'
    },
    xAxis: {
        categories: [
            'Attitude',
            'Identity',
            'Role',
            'Agility',
            'Fairness',
            'Conflict'
        ],
        crosshair: true
    },
    yAxis: {
        min: 0,
        max:100,
        tickInterval:10,
        title: {
            text: 'Rainfall (mm)'
        }
    },
    tooltip: {
        headerFormat: '<span style="font-size:10px">{point.key}</span><table>',
        pointFormat: '<tr><td style="color:{series.color};padding:0">{series.name}: </td>' +
            '<td style="padding:0"><b>{point.y:.1f} mm</b></td></tr>',
        footerFormat: '</table>',
        shared: true,
        useHTML: true
    },
    plotOptions: {
        column: {

                style: {fontWeight: 'bolder'},
                formatter: function() {
                    return "hello";
                },  
                inside: true,
                rotation: 270
            },
            pointPadding: 0.1,
            groupPadding: 0.1
        }
    },
    series: [{

    }]
};
var obj = {},
    exportUrl = options.exporting.url;
obj.options = JSON.stringify(options);
obj.type = 'image/png';
obj.async = true;

$.ajax({
    type: 'post',
    url: exportUrl,
    data: obj,
    success: function (data) {
        var imgContainer = $("#imgContainer");
        $('<img>').attr('src', exportUrl + data).attr('width', '250px').appendTo(imgContainer);
        $('<a>or Download Here</a>').attr('href', exportUrl + data).appendTo(imgContainer);
    }
});

高图上的图片为

Answer 1

而不是使用（在plotOptions - ＆gt;系列 - ＆gt; dataLabels中）：

formatter: function() ...

使用此：

format: "Hello",

请参阅：http://api.highcharts.com/highcharts#plotOptions.bar.dataLabels

高图表数据标签格式化程序无法正常工作
