I have the following dataset: Time EcNo 12:54:09.000 -14.47 12:54:10.000 -17.96 12:54:11.000 -15.97 12:54:12.000 -14.61 12:54:13.000 -12.68 12:54:14.000 -10.73 12:54:15.000 -10.54 12:54:16.000 -11.62 12:54:17.000 -12.49 12:54:18.000 -11.12 How would I plot EcNo on Yaxis vs Time(x axis)

问题 I have Pandas DataFrame (loaded from .csv) with Date-time as index.. where there is/have-to-be one entry per day. The problem is that I have gaps i.e. there is days for which I have no data at all. What is the easiest way to insert rows (days) in the gaps ? Also is there a way to control what is inserted in the columns as data ! Say 0 OR copy the prev day info OR to fill sliding increasing/decreasing values in the range from prev-date toward next-date data-values. thanks Here is example 01-03
