I want to draw the two plots on the same graph, how can I use gnuplot to realize that? Thank yu very much.

Solution

  • You could get two plots on the same graph in one plot command with two datafile arguments, separated by a comma. For instance

      plot [-1:5] 'data1.txt' with points, 'data2.txt' with points

    would get you something like this:
