    1. 366.196

      watch out: the average is heavely influenced by the system way of working -> when no new value, then no storage

      Qualitatively: look at the transient with high resolution

    1. Aggregated

      negative current ? could be: * calibration error; precision error * could also be brake current -> freeze machine to non-moving status

    2. Current

      Thoughts multi axis: * think about same unit but different range -> multiaxis (e.g. kV vs V) or normalize in 1 value * organize also signal picking: checkbox, or combox, or accordion tree

    1. Operating

      Depending on type of insight to show, chose right representation i.e. cumulative vs derivative.

      Also saisonality bar chart would make sense (day, week, month, etc).

      Additionnally, think about 0 time : start of year, custum, etc.

    1. MG7

      Idle engine (maintenance). Some measures are following the outside temperature trend, particularly heatwaves are visible. However, some other curves seems to be stable and regulated. It could be that the cooling system is shared among the engines. More specific, it could be that the water flow is the same for all machines. It would be interesting to observe, whether the operation of other engines affects temperature variation in this plot.

    1. fig = BigDataBoxPlot(df=df)\ .compute_boxplot_trace()\ .compute_outliers_trace()\ .get_figure( title="MG5 Temperature", xaxis_title="temperature [°C]", height=800 )\ .show(renderer="notebook")

      The temperature on the same object "Führungslager" seems to be different depending on the circular segment. This is probably due from the calibration which should not be that precise.
