我有一个 CSV 文件，其中包含以不同速度测量的值。我想将其显示为带有多条连续线的单个图表。
以下是记录的数据示例：
"date","Value button A","Temperature room1","temperature room2","Hygrometry","CO2 room1"
2012/12/22-11:34,,21.6,,40,390.08
2012/12/22-11:35,,21.6,,40,390.08
2012/12/22-11:36,,21.6,19.7,40,390.08
2012/12/22-11:37,,21.6,,40,390.08
2012/12/22-11:38,,21.6,,40,390.08
2012/12/22-11:55,,22,,40,390.08
2012/12/22-11:56,,22,,40,390.08
2012/12/22-11:57,,22.1,19.9,39,390.08
2012/12/22-11:58,,22.1,,39,390.08
2012/12/22-12:11,,22.3,,39,390.08
2012/12/22-12:12,,22.3,,39,390.08
2012/12/22-12:13,,22.3,,39,390.08
2012/12/22-12:14,,22.3,19.8,40,390.08
2012/12/22-12:37,,22.7,,39,390.08
2012/12/22-12:38,,22.7,,39,390.08
2012/12/22-12:39,,22.7,20.2,39,390.08
我的图表应该有带日期的 x 轴和带值的 y 轴。
正如您在此处看到的，“温度室 2”值仅在温度变化时存储。
有没有办法用这些数据显示连续线而不必填充 CSV 数据的空单元格？
