go-gnuplot

Simple-minded functions to work with gnuplot. go-gnuplot runs gnuplot as a subprocess and pushes commands via the STDIN of that subprocess.

See http://www.gnuplot.info for more informations on the exact semantics of these commands.

This is a fork of sbinet/go-gnuplot. The fork is motivated by the lack of maintenance to the original repo. This version will aim to extend on and fix bugs with the original implementation. The original API will not change so that this can become a drag and drop replacement of the original. See the issues for specific planned changes.

Installation

The go-gnuplot package is go get installable:

$ go get github.com/ckitagawa/go-gnuplot

import (
  "github.com/ckitagawa/go-gnuplot"
  "fmt"

func main() {
	fname := ""
	persist := false
	debug := true

	p,err := gnuplot.NewPlotter(fname, persist, debug)
	if err != nil {
		err_string := fmt.Sprintf("** err: %v\n", err)
		panic(err_string)
	}
	defer p.Close()

	p.PlotX([]float64{0,1,2,3,4,5,6,7,8,9,10}, "some data")
	p.CheckedCmd("set terminal pdf")
	p.CheckedCmd("set output 'plot002.pdf'")
	p.CheckedCmd("replot")


	p.CheckedCmd("q")
	return
}
