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;
• DATAFILE: path of a data file containing only a single block.

Usage

parallel-gnuplot datafilename gpfilename [tmpdirectory]

or

program_outputing_data | parallel-gnuplot gpfilename [tmpdirectory]

or

cargo run --release -- datafilename gpfilename [tmpdirectory]

where [tmpdirectory] is optional.

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

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