parallel-gnuplot

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:

```plain

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:

```gnuplot 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
