Streamlit中line_chart设置轴列报错，请求技术排查帮助

错误原因 #

你调用st.line_chart时，y参数传了嵌套二维列表[["blup_zwh","zwh2","zwh3","zwh4","zwh5","zwh6"]]，但Streamlit的line_chart接口中，y参数仅接受一维列名列表或单个列名字符串。这种嵌套结构会让程序无法正确识别DataFrame中的列，进而触发错误。

修复代码 #

st.line_chart(raport4, x="rasa", y=["blup_zwh","zwh2","zwh3","zwh4","zwh5","zwh6"])

额外验证建议 #

• 先执行print(raport4.columns)确认DataFrame中确实存在rasa以及所有指定的y轴列名，避免因拼写错误导致问题。
• 若仍有问题，可先提取目标列子集测试：subset = raport4[["rasa","blup_zwh","zwh2","zwh3","zwh4","zwh5","zwh6"]]，再将subset传入st.line_chart。
