我在如何将标签文本设置为左对齐时遇到问题.我想要做的是我希望我的标签与下一张图片相同，但我不知道 Options:{ 设置中文本对齐的位置.有没有人可以帮我解决它?我在 https://www.chartjs.org/docs 上找不到任何内容/latest/configuration/legend.html.提前谢谢你.

I'm having a problem on how to set the labels text align to left. What I want to do is I want my label same with the next picture but I don't know where in Options:{ settings for text align. Is there anyone can help me how to fix it? I can't find any on the https://www.chartjs.org/docs/latest/configuration/legend.html. Thank you in advance.

推荐答案

yAxis.ticks 标签可以通过定义 mirror: true 结合添加一些 padding.

The yAxis.ticks labels can be left aligned by defining mirror: true combined with adding some padding.

yAxes: [{
  ticks: {
    mirror: true,
    padding: 220
  },

要使标签在图表区域可见，需要在 图表布局.

To make the labels visible on the chart area, the same padding needs to be defined left of the chart layout.

layout: {
  padding: {
    left: 220
  }
},

请在下面查看您更改的代码.
