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.
The go-gnuplot package is go get installable:
$ go get github.com/ruphin/go-gnuplot/pkg/gnuplotpackage main
import "github.com/ruphin/go-gnuplot/pkg/gnuplot"
import "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
}
