Permissioning? Try a simple test.
set term png
set output "test.png"
plot sin(x)
set output
pwd
Now have a look in the directory pwd says gnuplot is using.

Thanks All. It is working. I see gnu Plot does create new file. Confusion becuase It overwrite file but does not update date & time. -- View this message in context: http://gnuplot.10905.n7.nabble.com/Gnuplot-doesnot-give-output-if-file-exist-tp18266p18303.html Sent from the Gnuplot - User mailing list archive at Nabble.com. |

Not so sure that you should blame gnuplot. As far as I know, file date
and time stats are set by your OS. Windows 8 has has two date/time
fields, creation and modification. I'm guessing that you have your
view set to creation.

I will check that & will let you know. My program is reading input data & trying to plot output to file every second. ________________________________ From: BBands [via Gnuplot] <ml-...@n7...> To: gnuuser4165 <s4...@ya...> Sent: Thursday, March 27, 2014 2:07 PM Subject: Re: Gnuplot doesnot give output if file exist Not so sure that you should blame gnuplot.
