chart.js 3.7.1 我的插件去哪里了？

Question

我从 chart.js 2.9.3 切换到 3.7.1，一些选项不再起作用。如果我看对了，像“图例”和“工具提示”这样的选项会转到“选项”下的插件？

但这对我不起作用。我想隐藏图例并自定义工具提示。

插件去哪儿了？任何帮助都会很棒。

谢谢，迈克尔

Answer 1

这是因为您的选项完全错误，选项中没有选项 object 和插件 object。选项 object 是一个包含所有选项的 object。所以如果你有一个自定义插件，你也需要在那里定义它。您的其余配置也仍然存在许多 V2 语法错误，例如标题和缩放配置。对于所有更改，请阅读 migration guide
