Hi again, ok so I tried with pure go 1.9 and checked if a simple test may work... And nothing is written. Maybe I'm doing something wring but, that's the test:

package main

import "github.com/Arafatk/glot"

func main() {
	dimensions := 2
	// The dimensions supported by the plot
	persist := false
	debug := true
	plot, _ := glot.NewPlot(dimensions, persist, debug)
	pointGroupName := "Simple Circles"
	style := "circle"
	points := [][]float64{{7, 3, 13, 5.6, 11.1}, {12, 13, 11, 1, 7}}
	// Adding a point group
	plot.AddPointGroup(pointGroupName, style, points)
	pointGroupName = "Simple Lines"
	style = "lines"
	points = [][]float64{{7, 3, 3, 5.6, 5.6, 7, 7, 9, 13, 13, 9, 9}, {10, 10, 4, 4, 5.4, 5.4, 4, 4, 4, 10, 10, 4}}
	plot.AddPointGroup(pointGroupName, style, points)
	// A plot type used to make points/ curves and customize and save them as an image.
	plot.SetTitle("Example Plot")
	// Optional: Setting the title of the plot
	plot.SetXLabel("X-Axis")
	plot.SetYLabel("Y-Axis")
	// Optional: Setting label for X and Y axis
	plot.SetXrange(-2, 18)
	plot.SetYrange(-2, 18)
	// Optional: Setting axis ranges
	plot.SavePlot("2.png")
}

Launching:

go run test.go
cmd> plot "/tmp/go-gnuplot-803798025" title "Simple Circles" with circle
res> 68
cmd> replot "/tmp/go-gnuplot-313721812" title "Simple Lines" with lines
res> 67
cmd> set title "Example Plot" 
res> 26
cmd> set xlabel 'X-Axis'
res> 20
cmd> set ylabel 'Y-Axis'
res> 20
cmd> set xrange [-2:18]
res> 19
cmd> set yrange [-2:18]
res> 19
cmd> set terminal png
res> 17
cmd> set output '2.png'
res> 19
cmd> replot  
res> 9
[patachou@patrice-desktop tensortest]$ ll 2.png
ls: impossible d'accéder à '2.png': No such file or directory

I'm trying to inderstand, I copy paste the all commands in gnuplot and it works... So what's the problem ?

[metal3d]

It seems that now... It works with that patch, but I need to kill gnuplot after a while to let the command release and write png file. That's very strange...

diff --git a/common.go b/common.go

But something strange appears... If I launch

@metal3d I am incredibly sorry for the late reply.
I literally tested the example again and it works fine for me.
If you still face any issues then let me know.

Little improvement : I like glot but when I had take a short after ~20 sec my terminal response me without open gnuplot image. please speedup glot it take ~20-30 sec on average to draw a graph

@ali2210 I am sorry you found the software to be a bit slow.
I think it's probably because of the external dependencies of Glot.

So a lot of this has to be deeply ingrained into the software.

I am super busy with work these days but I would encourage you to try glot and see if you might find something interesting.

Thanks for the comment.

I'm having a problem with mapping 2 dimensional datasets; I'm using go1.16.2 linux/amd64; In general, if I declare an array as:

var PointList [2][]float64

It will silently not plot. Perhaps I'm off-base here, but... ???
