intput file tricks

logscale y 2

use "-1" to take place of blank input cells. (out of y-axis range)

one script example:

set terminal postscript enhanced "Helvetica"11 #11 could control the font size

set pointsize 0.7

set key right bottom

set logscale x 2

set term postscript color

set xrange [1:128]

set xlabel "number of nodes (MPI Procs)"

set xtics("1" 1,"2" 2,"4" 4,"8" 8,"16" 16,"32" 32,"64" 64)

set grid xtics ytics mxtics mytics

set style line 1 lt 1 lw 3 pt 4

set style line 2 lt 1 lw 3 pt 4

set style line 3 lt 2 lw 3 pt 6

set style line 4 lt 2 lw 3 pt 6

set style line 5 lt 3 lw 3 pt 8

set style line 6 lt 4 lw 3 pt 1

set style line 7 lt 5 lw 3 pt 2

set style line 8 lt 6 lw 3 pt 3

set style line 9 lt 7 lw 3 pt 5

gsview/gs. eps <-->png

Windows

将jpeg,png,gif转换为eps格式，推荐使用bmeps命令行工具

eps ---> jpeg ...

gswin32c -dBATCH -dEPSCrop -sDEVICE=png256 -sOutputFile=tiger.png tiger.eps

Linux

png --> eps (Imagemagik)

sudo apt-get install imagemagik

convert tiger.png tiger.eps

eps --> png (GhostScript)

gs -dBATCH
-dEPSCrop -sDEVICE=png256 -sOutputFile=tiger.png tiger.eps

epstopdf
(better choice, higher resolution)

epstopdf
MKL_Strong_Scalability.eps (default output the same file name with pdf extension, *.pdf)
