HI , Dear Arun Peri For graph designing their are many tools in NS2.... like xgraph, trace graph, gnuplot etc and in windows environment there is a good one that is sigmaplot. They can be easily downloaded from internet. For linux version for NS2... Gnu plot is good one and easier one also. Thats why I recommend you to use gnuplot. becasue tracegraph and xgraph have not much options. For Gnuplot I can help you as I can tell you how to start making simple graph in gnuplot. And I am sure if you will be able to design a simple graph than it will not be much difficult to enhance your graph expertise.... STEPS for use and design for gnuplot. 1. If you are using NS2 on LInux system then GNUPLOT will be there by default. If you are using NS2 on windows system through cygwin then I am not sure about that. YOu can check it through typing GNUPLOT on terminal window . If you will get any file missing message like file is not specified than it means gnuplot is installed and dont have to reisntall it. ALternatively you can download it from. http://sourceforge.net/project/showfiles.php?group_id=2055 you will need .tar.gz for linux and .zip for windows. 2. Installation is very easy. You will find easy methods through foloowing links http://homepage.mac.com/marco_coisson/gnuplotGUI/getting_gnuplot.html http://www.sarcheck.com/gnuplot/billh.htm http://www.duke.edu/~hpgavin/gnuplot.html (GNUPLOT TUTORIAL) only in case of windows system you will need instalation and download, otherwise no need. 3. After confirming installation. you must gave to check the environment variable. in basch file. 4.Following files will be related with your work a. Graph.p (code file for gnuplot) b. Graph.tr ( trace file from which gnuplot will take readings for ploting a graph-- you have to take your readings from your code first coloumn is always X-axis and second coloumn is Y-axis and son on ) c. Graph.eps ( actual graph image file --can be generated after running the graph.p file --. It is eps file extension. you can only open in linux . If windows you can open it through IRFAN VIEW software otherwise ADOBE ILLUSTRATOR can also open this file on windows) 5. Now put the graph.p file in the folder where your graph.tr file (yours) is available and from terminal window go to that destination and just write GNUPLOT on terminal window you will get GNUPLOT> . 6. please also check the trace file path in GRAPH.P file. it is necessary to provide file path there in code file. 7. just write GNUPLOT> load "graph.p" 8. and you will have a graph. " COngratulations on your having a graph successfully" 9. you can exit from gnuplot through EXIT command. 10. for remaining commands for Graph plottiong. you have to explore its tutorial, mailing list for ns2 (I recommend you to join the mailing list of libnux. Follwing links can give you much information you need. http://t16web.lanl.gov/Kawano/gnuplot/index-e.html http://www.gnuplot.info/ ==========================SAMPLE FILE FOR GRAPH.P ============================= set title "XYZ" set xlabel "SEC(Seconds) " set ylabel "BW" set xrange [0:1300] set yrange [0:110] #set multiplot #set size 0.5, 0.5 #set origin 0.0, 0.5 set grid set boxwidth 20 #plot "/home/XYZ/ns-allinone-2.33/ns-2.33/mygrid/graph/abc.tr" using 1:2 with lines lt 1 lw 2 title 'My Work' plot "/home/XYZ/ns-allinone-2.33/ns-2.33/mygrid/graph/abc.tr" using 1:2 title 'Previous Work' with linespoints , \ "/home/XYZ/ns-allinone-2.33/ns-2.33/mygrid/graph/abc.tr" using 3:4 title 'My Work' with linespoints #set tmargin 0 #set bmargin 0 set term post eps enhan "Helvetica" 60 set out "combine-curve-time.eps" #set nomultiplot ====================================================== first row represents X axis and second row represents Y axis ====================================== TRACE FILE format ===================== 10 9 30 12 50 27 70 28 90 33 110 39 130 43 150 44 170 48 190 52 210 57 320 58 330 60 370 65 450 66 470 68 490 75 530 79 550 81 1280 100 ================================= Hope it will help you.
