我有一个CSV文件，其中包含以不同速度进行调整的值。 我希望将它显示为具有多个连续线的单个图表。
以下是记录数据的示例：
"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
我的图表的x轴应为日期，y轴应为值。
正如您在此处所见，“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的行而不必填充CSV数据的空单元格？
