I am new to Mathematica. Please help me. I need to plot data file that has 2 columns of the data with length 401 points or more. I need that X of the graph will be first column and Y of the graph will be second column of this data file. Actually, the first column begins from 9.2e7, with constant step. The second column has different negative numbers with float point.
Any links would be appreciated.
Thanks in advance,
