parallel-gnuplot

Version info Build Status Build status

Parallel calls to GNUPlot. Calls the same GNUPlot script once for each data file block. Please, note GNUPlot has copyrights, and parallel-gnuplot is not a modified version of GNUPlot.

GNUPlot variables

parallel-gnuplot sets some GNUPlot variables:

  • INDEX: block index, starting at 0 if --initial was not set;
  • CONTINUOUSINDEX: block index, starting at 0;
  • DATAFILE: path of a data file containing only a single block.

Usage

parallel-gnuplot -d datafilename0 -d datafilename1 [-d ...] -g gpfilename

or

program_outputing_data | parallel-gnuplot -g gpfilename

or

cargo run --release -- -d datafilename0 -d datafilename1 [-d ...] -g gpfilename

Use flag -h for more help.

Example

data.txt:

# block 0:
0 0
1 1
2 2
3 3
4 4


# block 1:
0 0
1 2
2 4
3 6
4 8

script.gp:

set terminal png size 800,600
set encoding utf8

set xrange [0:4]
set yrange [0:8]

set key left top
set output sprintf("%d", INDEX).'.png'

plot DATAFILE0 with lp lw 2 pt 7 ps 3 title sprintf("Block %d", INDEX)

You can call: parallel-gnuplot -d data.txt --g script.gp or cargo run --release -- -d data.txt -g script.gp or something like cat data.txt | parallel-gnuplot -g script.gp
