Highcharts.chart（'container'，{

series: [{
        useHTML:true,
    type: 'treemap',
    layoutAlgorithm: 'squarified',
    data: [{
        name: 'A',
        value: 6,
        colorValue: 1
    }, {
        name: 'B',
        value: 6,

    }, {
        name: 'C',
        value: 4,
        colorValue: 3
    }, 
    {
        name: 'Gnscweoihciohoihrioghoierhgoierhoiehgoirehgoirehoih',
        value: 1,
        colorValue: 7
    }]
}],
title: {
    text: 'Highcharts Treemap'
}

}）;

我尝试使用HTML：true属性，但没有帮助。 Word-Break也未得到应用

Answer 1

需要进行2次更新：

1。您必须在dataLabels属性中添加series属性

您在useHTML: ture之外添加了dataLabels属性，所以请像下面这样使用：

dataLabels: {
    useHTML: true,
    formatter() {
        return '<div>'+this.point.name+'</div>';
    }
},

2。为数据标签添加css

.highcharts-data-label span {
    white-space: normal !important;
}

检查您的代码内容中的工作示例：

Highcharts.chart('container', {
    series: [{
        dataLabels: {
            useHTML: true,
            formatter() {
                return '<div>'+this.point.name+'</div>';
            }
        },
        type: 'treemap',
        layoutAlgorithm: 'squarified',
        data: [{
            name: 'A',
            label: "A",
            value: 6,
            colorValue: 1
        }, {
            name: 'B',
            value: 6,
            colorValue: 2
        }, {
            name: 'C',
            value: 4,
            colorValue: 3
        }, {
            name: 'D',
            value: 3,
            colorValue: 4
        }, {
            name: 'E',
            value: 2,
            colorValue: 5
        }, {
            name: 'F',
            value: 2,
            colorValue: 6
        }, {
            name: 'This is demo of my code, are you happy',
            value: 1,
            colorValue: 7
        }]
    }],
    title: {
        text: 'Highcharts Treemap'
    }
});

        Tree maps are great tools for comparing values that are part
        of a whole, or for showing hierarchical data. This example
        is a simple tree map with no hierarchy, showing the value
        differences with rectangle sizes and using a color axis.
