M.Aman · 05-30-2019, 12:27 AM

hi,

Is there anyway i can save my plots generated in xgraph using ns2 and centos7?

I tried using gnuplot as well, but it gives me the following error,
Cannot open load file 'graphPlot'
"graphPlot", line 0: util.c: No such file or directory

CAn anybody guide me here?

Xgraph options : Close - Hdcpy - About.

Open the "Hdcpy" dialog, and type a directory/file-name. Default is Postscript.
I typed /home/knudfl/2020xgr/1
.... The result is attached as 1.ps.txt . Rename to 1.ps , and open.

Alternatively (and easier, may be) : Take a screenshot with ImageMagick :

Code:

$ import screen$RANDOM.jpg

As shell script :

Code:

#!/bin/sh
import screen$RANDOM.jpg;
exit 0;

Make the script executable. copy to /usr/local/bin/, and you can create screenshots any size. Comes with a cross-hair for exact cut.

Simple gnuplot example ...

Code:

$ gnuplot Leach.gp

And even simpler :

Code:

$ gnuplot
gnuplot> plot "sim.data"

Thankyou Knudfl. When i click "Hdcpy" the xgraph closes and nothing happens. In the terminal i get a message of Segmentation fault (core dumped). Can you guide me here?

Re #4.

Xgraph is picky with compilers. The "GCC-4.9.3 package" works for me in CentOS 7.
Compiler package = gcc49-c++-4.9.3-1.el6.x86_64.rpm
https://drive.google.com/file/d/1Pwq...ew?usp=sharing
... Provides /usr/bin/{gcc49, g++49}

Download, and install :

Code:

# yum install Downloads/gcc49-c++-4.9.3-1.el6.x86_64.rpm

Build a new 'xgraph' executable :

Code:

cd ns-allinone-2.35/xgraph-12.2/
rm -f depcomp
ln -s /usr/share/automake-1.13/depcomp
make clean
export CC=gcc49 CXX=g++49 && ./configure
make
# make install

My test today, CentOS 7 :
Select Hdcpy in the Xgraph window.
Type ./1.ps in "File or device name" ... and click OK →
→ The file 1.ps is created in the current directory.

... For saving colors, see post #2 ( $ import screen$RANDOM.jpg, etc.)
