Dear all,

I would like to plot several output.txt files (2nd and 3rd column) on the same graph. The configuration of one .txt files are bellow. The number of lines can be diferent between the .txt files but both headerlines are equal. The 0 values on the firsts substeps can be ignored (they will always be present in all .txt files so can be assumed as part of headers)

I will have for example output1.txt, output2.txt, output3.txt.....

Thanks in advance.

Best,
