javascript - d3Plus 和环绕文字

标签 javascript d3.js word-wrap d3plus

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

The Error

最佳答案

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()

那是 d3 版本 3 语法，而看起来您使用的是 d3 版本 4。

看起来您想要版本 4 的 this library(它特定于文本换行)。

下面是一个将新 API 与您的代码片段合并的示例:
