Hi everybody,
I’m new in the forum, and it is only recently that I using root.
I would ask help you,
I have a data file, with more columns and more blocks, for example
1 2 3 4 5
6 7 8 9 1
2 3 4 5 6
1 2 3 4 5
9 8 7 6 5
6 5 4 3 2
1 2 5 7 8
6 5 3 6 7
9 5 4 3 2
More columns and more blocks with more lines.
I have to produce a Graph with for example only the 2nd and 4th column, and only for 2nd block. How can i do it? possibly using command line.
Thank you very much!!!
