保存 gnuplot 图而不显示绘图

  • 772

我有一个数据文件（data.txt）。我可以使用 gnup 命令绘制数据。喜欢;

gnup -p data.txt -xl 'Hours' -yl 'Data (m)'

执行上述命令后，我需要保存绘图（例如 png 格式）而不绘制数据。那可能吗？

gnuplot

    gnuplot有一个set output我用来保存我的情节副本的命令： 

    #!/bin/bash 
# Run this script after synching the Palm with $HOME/Visor/.last

# Weight - extract my weight data fron the Visor, clean it
# up, and feed it to gnuplot

target=$HOME/Visor/var/Weight
visorhome="$HOME/Visor"
gnuplotdata="${target}.pltdata"
gnuplotout="${target}.ps"

# ... data prep omitted - data to plot is in $gnuplotdata 

gnuplot <<EOF
set title "Weight and running average, in kilograms, for Walt Sullivan"
set timefmt "%y/%m/%d"
set xdata time
set format x "%y/%m/%d"
plot "$gnuplotdata" using 1:2 with linespoints, "" using 1:3 with linespoints;
pause 10 "Plot will close in 10 seconds, see $gnuplotout"
set terminal postscript enhanced color landscape
set output "$gnuplotout"
replot
EOF

exit 0

    要了解更多信息，请键入： 

    $ gnuplot
gnuplot> help set output
 By default, screens are displayed to the standard output. The `set output`
 command redirects the display to the specified file or device.
