案例参考：零代码搭建物联网监控大屏你的CSV里只记录了一个时间点的一条数据吧；横轴是时间，按理说你的CSV里有几个时间点，横轴就应该显示几个，若只有一个，请检查你的数据源。或者构造多条测试数据验证下效果：[{"Time": "20250210T053550Z","Temp1": "51.1","Temp2": "52.2","Temp3": "53.3","Temp4": "54.4"},{"Time": "20250210T054550Z","Temp1": "61.1","Temp2": "62.2","Temp3": "63.3","Temp4": "64.4"},{"Time": "20250210T055550Z","Temp1": "71.1","Temp2": "72.2","Temp3": "73.3","Temp4": "74.4"}]
