I want to analyze data files with the following format
0.01 1.00 11.00 21.00 0.02 2.00 12.00 22.00 0.03 3.00 13.00 23.00 0.04 4.00 14.00 24.00 0.05 5.00 15.00 25.00
I want to create a plot with

And if it is possible, is it easy to do the same with lines instead of columns or perform other simple mathematical calculations (multiplication, taking the logarithm, etc.)?
