opetate according to "Makefile"

[orzrunningsnail]

Sir, thank you very much! I have known how to operate, after reading the "Makefile".But unfortunately, I didn't get the same result as your "results.png". There are some problems: When I execute the command "./ns bbr_test.tcl > outbbr.txt " , the result is "picture 1".More worse, when I excute the command "python plot.py outbbr.txt" , the result is "picture 2,3". I don't know how to slove these problems. If you could give me some methods or suggestions, I will appreciate it! Thanks for your time! Looking forward for your reply.
