asciigraph

Go package to make lightweight ASCII line graphs ╭┈╯.

Installation

go get github.com/guptarohit/asciigraph

Usage

Basic graph

package main

import (
    "fmt"
    "github.com/guptarohit/asciigraph"
)

func main() {
    data := []float64{3, 4, 9, 6, 2, 4, 5, 8, 5, 10, 2, 7, 2, 5, 6}

    conf := map[string]interface{}{}

    graph := asciigraph.Plot(data, conf)

    fmt.Println(graph)
}

Running this example would render the following graph:
