Hi all,

I would like to save data from several result files (plot over line of 3 .plt files in my case) in the same .csv file. On the attached picture, I would like to save the data corresponding to the 3 lines (dumpR7, dumpR9 and dumpR12) in the same .csv file (1 column for each line):

Output wished .csv with the following shape:  
col1, col2, col3, col4  
Z, dumpR7 - T\_d2, dumpR9 - T\_d2, dumpR12 - T\_d2

I tried:

- Select the 3 **Plot Over Line** and **Save Data** but it only save 1 line.
- **Group Dataset** and then **Save Data** but it only save 1 line.
- 

Thank you in advance for your help,  
Sincerely

.csv format is just not able to handle multi dimension data.

You get a certain number of lines and a certain number of collumns.

If you data is truly 2D, then you should be able to run merge blocks or append attributes before saving to csv
