ns2 시뮬레이션에서 satcom에서 xgraph를 그리는 방법

Question

SAT-COMM에 대한 네트워크를 시뮬레이션하는 동안 xgraph에 출력을 표시하려고합니다. 나는 그렇게 할 수 없다. 내가 얻는 오류는 "Error in file `outsat.tr' at line 1085: Unknown line type"입니다. 안내해주십시오. 주어진 아래

는 xgraph을 통해 플롯 할 수없는 코드

# Example script that mixes geo satellites with some polar satellites: 
# One plane of Iridium-like satellites, one geo satellite, and two terminals 
# pinging one another on it 
# In the script, since this is not a full constellation, the LEO satellites 
# eventually move out of range of the terminals and packets get dropped

Answer 1

추적 파일 (outsat.tr)입니다. 다른 파일에 시간과 처리량을 수동으로 기록해야합니다. 그 파일은 xgraph로 열 수 있습니다.
