Your gnuplot build has neither the png nor the pngcairo terminal
compiled into it. It looks like a rather minimal build, did you compile
it yourself?

You need to install the headers files for libgd (for png, jpeg, gif)
and/or libcairo/libpango (for pngcairo etc.) first. (named ##-dev in
most distributions.) Then rerun ./configure, the summary on the last
page tells you if all necessary libraries for the respective terminals
have been found. make, make install, you get it.

If it came with your distribution (which one?), you probably picked the
minimal X11-only gnuplot build or so. Check if there's another one
available in your package manager.

Thanks for the reply.

Earlier i have installed gnuplot by downloading "gnuplot-4.6.6" and following  this "https://techtravelo.wordpress.com/2013/10/04/gnuplot-in-ubuntu-12-04-installing/"  post.


Now i have uninstalled it by "make uninstall".
when i gave  
$ gnuplot                  its showing:




The program 'gnuplot' can be found in the following packages:
 * gnuplot-nox
 * gnuplot-x11
Try: sudo apt-get install <selected package>



Now please tell me how should i install gnuplot so that it will have png support?
Please tell me complete procedure because i am not all good in linux.

You very nearly succeded. You only have to install the developer library
packages mentioned in the end of that page before running "./configure
&& make && make install". But nevermind ...

Installing the package supplied by Ubuntu is certainly the simplest
solution. gnuplot-x11 also has the interactive wxt/qt terminals compiled
in, i guess you want that.

Just

 sudo apt-get install gnuplot-x11

and give your password. If you have sudo rights. Otherwise you need to
get hold of your admin anyway, because you then also cannot install the
developer library packages mentioned above to compile it yourself.

hey thanks by "sudo apt-get install gnuplot-x11" 
it has png terminal.

But can you tell me how can i copy it to "/usr/local/bin"?
Because where i need this png terminal it is showing now :



ns: finish: couldn't execute "/usr/local/bin/gnuplot": no such file or directory
    while executing
"exec $gnuplot_app_path_ -persist [$self command-filename $graph] &"
    (procedure "_o14" line 11)
    (gnuplot protected-plot-after-command-file line 11)
    invoked from within
"$low_level_plotter_ protected-plot-after-command-file $graph"
    (procedure "_o13" line 32)
    (postscript protected-plot line 32)
    invoked from within
"$self protected-plot $graph"
    (procedure "_o13" line 7)
    (PlotDevice plot line 7)
    invoked from within
"$plot_device plot $self"
    (procedure "_o736" line 19)

    (Create_graph finish line 59)
    invoked from within
"$graph finish"
    (procedure "finish" line 9)
    invoked from within
"finish"


Can you please help further?

You better change that variable $gnuplot_app_path to be
"/usr/bin/gnuplot", instead of "/usr/local/bin..."

What kind of a program is that?

Actually its a tool NS2(NetworkSimulator 2).
And i don't where it is taking "/usr/local/bin".
After running it just shows that message.
