Go package to make lightweight ASCII line graphs ╭┈╯.
go get github.com/guptarohit/asciigraph
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 ┤ ╰╯ ╰╯╰╯
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.
go install github.com/guptarohit/asciigraph/cmd/asciigraph
or download binaries from the releases page.
Feed it data points via stdin:
$ seq 1 72 | asciigraph -h 10 -c "plot data from stdin"

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"
