我使用'chartjs-plugin-data labels v2.1.0'插件，创建一个幸运轮，你需要在标签栏中用img替换文本，怎么做？
在常规JS中，标签行有值'2'，'3'，等等，那么我想推img我如何解决这个问题？

const spinBtn = document.getElementById("spin_btn");

似乎chartjs-plugin-datalabels不准备处理图像。
如果没有任何特定的原因，你可以使用chartjs-plugin-labels，它似乎更适合你当前的需求。
这是你的旋转轮，所有标签都有相同的图像（chartjs徽标）。如果你想改变任何图像或图像的大小，你可以改变插件选项。
