Creating Lightweight ASCII Line Graphs in Go

Introducing asciigraph: Creating Lightweight ASCII Line Graphs in Go

Have you ever wanted to create beautiful line graphs using ASCII art? Look no further! The asciigraph package, available in Go, allows you to create lightweight ASCII line graphs effortlessly. In this article, we will explore the features, usage, and versatility of asciigraph, providing you with the knowledge and tools to create visually appealing graphs.

Features and Functionality

asciigraph provides a simple and intuitive API to create line graphs. You can plot single series or multiple series of data points, customize the appearance of the graph, and even create colored graphs. The package offers flexibility in terms of data input, allowing you to provide data directly or stream data in real-time.

To get started, install the asciigraph package using the following command:

bash
go get -u github.com/guptarohit/asciigraph@latest

Once installed, you can begin creating line graphs using the asciigraph package. Here’s an example of creating a basic graph:

“`go
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 will generate a line graph representing the provided data points:

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

asciigraph also allows you to plot multiple series of data points. Here’s an example:

“`go
package main

import (
“fmt”
“github.com/guptarohit/asciigraph”
)

func main() {
data := [][]float64{{0, 1, 2, 3, 3, 3, 2, 0}, {5, 4, 2, 1, 4, 6, 6}}
graph := asciigraph.PlotMany(data)

fmt.Println(graph)

}
“`

Running this example will generate a line graph with multiple series:

6.00 ┤ ╭─
5.00 ┼╮ │
4.00 ┤╰╮ ╭╯
3.00 ┤ │╭│─╮
2.00 ┤ ╰╮│ ╰╮
1.00 ┤╭╯╰╯ │
0.00 ┼╯ ╰

asciigraph also supports creating colored graphs. Here’s an example:

“`go
package main

import (
“fmt”
“math”
“github.com/guptarohit/asciigraph”
)

func main() {
data := make([][]float64, 4)

for i := 0; i < 4; i++ {
    for x := -20; x <= 20; x++ {
        v := math.NaN()
        if r := 20 - i; x >= -r && x <= r {
            v = math.Sqrt(math.Pow(float64(r), 2)-math.Pow(float64(x), 2)) / 2
        }
        data[i] = append(data[i], v)
    }
}

graph := asciigraph.PlotMany(data, asciigraph.Precision(0), asciigraph.SeriesColors(
    asciigraph.Red,
    asciigraph.Yellow,
    asciigraph.Green,
    asciigraph.Blue,
))

fmt.Println(graph)

}
“`

Running this example will generate a colorful line graph:

Real-world Use Cases
