Most commonly, a time series is a sequence taken at successive equally spaced points in time. The original data has a float type time sequence (data of 60 seconds at 0.0009 second intervals), but in order to specify the ‘rule’ of pandas resample (), I converted it to a date-time type time series. return the transpose, which is by definition self Habe ich einige hierarchische Daten, die Böden in Zeitreihen-Daten, die wie folgt aussieht: df = pandas.
