asciigraph

Zig module to flush console ascii line graphs ╭┈╯

Crude derivation of the asciichart implementations in zig

Installation

Add asciigraph to your build.zig.zon:

zig fetch --save https://github.com/im-ng/asciigraph/archive/refs/heads/main.zip

Usage

const std = @import("std");
const asciigraph = @import("asciigraph");
const configs = asciigraph.options;
const colors = asciigraph.colors;

pub fn main() !void {
    var gpa = std.heap.GeneralPurposeAllocator(.{}){};
    const allocator = gpa.allocator();

    const c = configs.config{
        .rows = 1,
        .columns = 50,
        .height = 5,
        .offset = 0,
        .legendColor = colors.White,
        .legends = "X Axis",
        .caption = "Y Axis",
    };

    const matrix = try asciigraph.prepareMatrix(c.rows, c.columns, allocator);
    asciigraph.fillRandom(matrix);

    try asciigraph.PlotGraph(allocator, matrix, c);
}

Examples

This repository contains a number of ready-to-run examples demonstrates the use of the asciigraph.

• Basic
• Sine Wave
• Stream - Real time data
• Rainbow

git clone https://github.com/im-ng/asciigraph.git
cd asciigraph/examples
zig build

Run one of the sample use command zig build {sample_name} from examples folder.

zig build basic
zig build sine
ping -i1 google.com | grep -oP "time=\K\d+\.?\d*" --line-buffered | zig build stream

Real time plot
