Import timeseries csv data?

H. Koge
Posted 4 years ago

Hello, I am usually MATLAB user. I am considering switching from MATLAB to Mathematica.

Now please help me, I am very struggling to import time series csv in Mathematica. Very first step for users except me, but it takes too many time...

The data format is

2020, 10, 27, 3, 45, 14.579, 38.1726, 143.41, 3390., 47071, 9999, -7711.6, -22813.8, 47340.9, 93.54, -0.4, -0.31 ...

First 1-6 is YYYY,MM,DD,hh,mm,ss, and followings are each sensor data.

I cannot found how to import this data and plot.

Try this for a start:

FILENAME = "test.csv";
Column[
MapIndexed[DateListPlot[{#1}, PlotLabel -> Row[{"Column ", First[#2]}]] & , 
 First[
   Import[
     FILENAME, {"CSV", "Data"}
 ] ] /.   {yyyy_Integer, MM_, dd_, hh_, mm_, ss_, (data__)?NumberQ} :> 
          Thread[{DateObject[{yyyy, MM, dd, hh, mm, ss}], {data}}]]]

The answer from Rolf imports and plots the data in one step. To just import the data

data = First[Import[FILENAME, {"CSV", "Data"}]] /. 
  {yyyy_Integer, MM_, dd_,  hh_, mm_, ss_, (data__)?NumberQ} :> 
    Thread[{DateObject[{yyyy, MM, dd, hh, mm, ss}], {data}}]
