d3Plus 和环绕文本答案

【问题标题】：d3Plus and wrapping textd3Plus 和环绕文本
【发布时间】：2019-01-19 11:51:22
【问题描述】：

我正在尝试使用 D3plus 包装文本 - 我开始了解如何在 SVG 包装中制作文本。但是，我不断收到与 d3Plus 或我的代码有关的错误 - D3 的文档非常稀少，所以我希望就我出错的地方获得一些帮助。干杯。

【解决方案1】：

如果您查看导入d3plus 时发生错误的行，您会看到这一点；

 d3.scale.ordinal()

这是 d3 version 3 语法，而看起来您使用的是 d3 version 4。

看起来你想要this library 用于版本 4（它特定于文本换行）。

这是一个将新 API 与您的代码 sn-p 合并的示例：

【讨论】：

经过一番挖掘，d3Plus 不存在（据我所知）...您对文本换行还有其他简单的建议吗？
是的，我试过了。但我得到d3plus.textBox is not a contructor 的错误
@FeelingLikeAJabroni，添加了运行代码 sn-p 以了解如何使用该库。
谢谢你，我现在就试试看……但是你为什么要注释掉重要的代码才能让它工作呢？
@FeelingLikeAJabroni，我将其注释掉，因为您的代码示例不完整且未定义这些变量。此外，我的示例代码应该足以让您将我的“数据”替换为team + filterss
