# 任务目标

分析`/project/stats/chart/chat`接口在处理请求参数`dimension`等于"year"的场景下，输出参数里面的y值不正确的问题。再顺便看看下面这几个接口是不是也有问题：`/project/stats/chart/token`、`/project/stats/chart/dislike`、`/project/stats/chart/user`、`/project/stats/chart/skill/usage`、`/project/stats/chart/feedback`、`/project/stats/chart/mcp/usage`、`/project/stats/chart/skill/usage`。

## 开发规范

参考文档:"E:\gitea\skills\mis-agent-spec\SKILL.md"。

## 入口类

ProjectStatsController.java

## HTTP请求的输入和输出信息
