#3333 — Plot datafiles in bulk

Hi,

I'd like to plot multiple .csv files in bulk, regardless of their names:
20151221-Log.csv
20160315-Log.csv
20160601-Log.csv
...

Each of them contains data in the form:
1,18711,9501,888,0.00,2.19
2,18726,9501,897,0.00,2.19
3,18741,9501,900,0.00,2.17
...


Is there an easy way to do this without having to specify the name for each individual file and without having to join the files ?

Something like using a wildcard in DOS:
 plot '*-Log.csv' u 1:2 ,  '' u 1:3
or even:
 plot '*.csv' u 1:2 ,  '' u 1:3

Thanks

"plot" obviously does not support wild cards, but something like

   fnlist = system("ls *.csv")
   n = words(fnlist)
   fname = word(fnlist,i)
   plot for [i=1:n] fname(i) using ....

could work.

Or
    fnlist = system("ls -1 *.csv")
    plot for [FILE in fnlist] FILE

I keep forgetting that "for" can directly iterate through a list of
words. Thanks!

Also works on MS windows, btw., the corresponding command is "dir /B
*.cvs".

Doesn't

   print system("dir /B *.csv")

give the expected output any more? Win XP is sort of not supported
any more, but i guessed it still works mostly ...

Hi,

Finally got it working, thanks for your help.

But there's something I still don't understand:
   print system("dir /B *.csv") works fine, but
   print system("dir C:\temp1 /B *.csv") does not what's expected.

What am I doeing wrong ?

It's

    dir /B C:\temp1\*.csv

and you have to give double backslashes inside double quotes.
See "help quote marks".
