Numeric data without accompanying metadata are useless -- it's really that simple. The very minimum would be axis labels and the information where the data originated from and what they represent (e.g., measurements of a sample with some method or results from some calculations). | Numeric data without accompanying metadata are useless -- it's really that simple.
