如何使类别标签看起来不错？我需要能够显示每个类别的全文，但我找不到一种方法来做到这一点。我尝试添加
并使用"useHtml"选项，但它不起作用提前致谢

"xAxis": {
    "categories": ["a very long long text ", "2another long text", "dda", "bbb", "aaa"],
    "allowDecimals": "0",
    "title": {
        "text": "Hello world",
        "offset": -350,
        "align": "left",
        "style": {
            "color": "red"
        }
    },    

删除"title=>offset"可以修复它。
