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}
    graph := asciigraph.Plot(data)

    fmt.Println(graph)
}

Running this example would render the following graph:

::

10.00 ┤ ╭╮ 9.00 ┤ ╭╮ ││ 8.00 ┤ ││ ╭╮││ 7.00 ┤ ││ ││││╭╮ 6.00 ┤ │╰╮ ││││││ ╭ 5.00 ┤ │ │ ╭╯╰╯│││╭╯ 4.00 ┤╭╯ │╭╯ ││││ 3.00 ┼╯ ││ ││││ 2.00 ┤ ╰╯ ╰╯╰╯

Command line interface

This package also brings a small utility for command line usage. Assuming $GOPATH/bin is in your $PATH, simply go get it then install CLI.

CLI Installation ^^^^^^^^^^^^^^^^

::

go install github.com/guptarohit/asciigraph/cmd/asciigraph

or download binaries from the releases <https://github.com/guptarohit/asciigraph/releases>_ page.

Feed it data points via stdin:

::

$ seq 1 72 | asciigraph -h 10 -c "plot data from stdin" 72.00 ┼ 65.55 ┤ ╭──── 59.09 ┤ ╭──────╯ 52.64 ┤ ╭──────╯ 46.18 ┤ ╭──────╯ 39.73 ┤ ╭──────╯ 33.27 ┤ ╭───────╯ 26.82 ┤ ╭──────╯ 20.36 ┤ ╭──────╯ 13.91 ┤ ╭──────╯ 7.45 ┤ ╭──────╯ 1.00 ┼──╯ plot data from stdin

..

Realtime graph for data points via stdin:

::

$ ping -i.2 google.com | grep -oP '(?<=time=).*(?=ms)' --line-buffered | asciigraph -r -h 10 -w 40 -c "realtime plot data (google ping in ms) from stdin" 8.26 ┤ ╭╮ 7.77 ┤ ││ 7.27 ┤ ││ 6.78 ┤ ││ ╭╮ 6.29 ┤ ╭╮ ╭╮ ││ ││ 5.79 ┤ ││ ││ ││ │╰╮ 5.30 ┤ ││ ││ ╭╮││ │ │ ╭ 4.81 ┤ ││ ││ ││││ │ │ │ 4.32 ┤ ╭╮ ││╭╯│ ╭╮ ││││ │ │ ╭╯ 3.82 ┼╮│╰─╯╰╯ │╭──╯╰─╯╰╯╰──╮ ╭───╮╭───╯ ╰──╯ 3.33 ┤╰╯ ╰╯ ╰─╯ ╰╯ realtime plot data (google ping in ms) from stdin
