[Kst] Trending from daily CSV Files KST-Plot Windows Version

Hello Barth,

thanks for your quick answer.
I've tried your suggestion but still have following questions  

- Attached is an example of "list of files".  Does extension must be .txt. or .csv?  
   Is file attached OK? 
- I tried both (.csv/.txt) but I couldn't  figure out how to define data source as "list of files".
   I've tried to configure data source via data wizard, but then it will be imported as a normal single  .csv file.  
   I would appreciate if you can send me a short description or some screenshots how to do this.
- If in "list of files" will be added a new CSV- file, does Kst2Plot will automatically online switch to the newest file
  and read datasets from this file? Or must the application be restarted?

Many thanks for your help.

Best Regards

Jörg

Yes, this can be done.

Make a file which is a list of file you want to append:

file1.csv
file2.csv
file3.csv

No blank lines.

Use this file which is the list of files as the data source instead of any of the individual files.  Kst will monitor if the last file in the list is growing, as normal.

Additionally, it will monitor the list of files.  If you append a new file to the list, it will add it, and start monitoring it for new data instead.

makes sense?
