Fitting Function with Multiple Files

Question

My Data: File 1:

2015-08-01 07:00    0.23    0.52    0.00    0.52    9   14.6    14.6 14.6   67  8.5 0.0 --- 0.00    0.0 --- 14.6    14.1    14.1    16.3    1016.2  0.00      0.0   156 0.22    156 0.0 0.00    0.0 0.003   0.000   23.9    39  9.1 23.4    0.05    23  1   100.0   1   1.8797836153192153  660.7143449269239

2015-08-01 07:00    0.23    0.52    0.00    0.52    9   14.6    14.6 14.6   67  8.5 0.0 --- 0.00    0.0 --- 14.6    14.1    14.1    16.3    1016.2  0.00      0.0   156 0.22    156 0.0 0.00    0.0 0.003   0.000   23.9    39  9.1 23.4    0.05    23  1   100.0   1   1.8797836153192153  660.7143449269239

..... and so on. So the csv. files are multiple days and from those days I created a scatterplot using 3:43:0 I used the 0as a dummy so I could use varialble linecolors (if I wouldn`t have done that the colors would have repeated themselfs after line 9)

The Scatter Plot looks great but now I want to fit a curve into the plot. There are 2 similar questions: Question 1 , Question covering the Fit Data from multiple files but when trying the cat or awk command I always end up with an error telling me cannot create pipe for data So what I tried was:

fit f(x) '< cat file1.csv file2.csv file3.csv file4.csv file5.csv' u 3:43:0 a,b

am I missing something here? Cou8ld this be a OS Problem? I run Windows 7.

Answer 1

Both cat and awk are Unix-commands. The windows-equivalent of cat is type. For instance, the following should work:

fit f(x) '< type file1.csv file2.csv' u 3:43:0 via a,b

If, for some reason, you need to use a tool like gawk (gnu-equivalent to awk), grep, or sed in windows, take a look at gnuwin32.
