Gnuplot flashing output X-window when generating Pdf

Question

I am running Gnuplot on Ubuntu 13.10 to generate some pdf plots.

Now I run a sample plot file1.gpl written as -

set xrange [0.000000:780121.000000]
set yrange [0.200000:4.800000]
set autoscale x
set key off
set style line 12 lc rgb '#808080' lt 0 lw 1
set grid back ls 12
set palette model RGB
unset colorbox
set object 1 rectangle from 404644.000000, 0.8 to 408665.000000, 1.2 fillcolor rgb "#FFB300" fillstyle solid 0.8
plot -1 title "COLOR_0" with lines linecolor rgb "#FF9B73"  linewidth 6 

And there is another file, which is like settings for me, used to generate the pdf output file.

set terminal pdfcairo size 12in,6in
set output "output.pdf"
replot
set output

I run the command as -

gnuplot file1.gpl settings.gpl

Now when I run this, it generates the PDF file correctly, without any problem. However a X-window flashes at the output momentarily which shows the plot. I would like to disable this momentarily flashing of the X-Window because I am running a plot generation in a script file, which results continuous flashing of output window.

Thanks !

Just switch the two files. At the moment the first plot command is carried out, the default interactive terminal is set.

Change your settings.gpl to

set terminal pdfcairo size 12in,6in
set output 'output.pdf'

and call

gnuplot settings.gpl file1.gpl
