UnicodePlotsSimple

Simple unicode plotting.

• Very simple unicode distribution
• Very simple unicode vertical histogram
• Very simple unicode heatmap
• Very simple unicode densitymap

I love the simple "flat" programming style in Julia. (I believe it was way overstated in C++ and this is much easier to understand.)

Example

Code:

import Pkg; Pkg.add(url="https://github.com/Cvikli/UnicodePlotsSimple.jl")
using UnicodePlotsSimple

distribution([0.3,0.2334,0.1,0.8], height=3, values=[0.3,0.2334,0.1,0.8])

rnds = randn(1000).+2
histogram(rnds, width=70, height=5, title="Random num generation histrogram", printstat=true)


xticks = ["a","b","c","h","p"]
yticks = ["a","b","c","h","p"]

data = [randn(5,5),randn(5,5),randn(5,5)]
desnitry = [rand(1:150,5,5),rand(1:350,5,5),rand(1:6,5,5)]

heatmap(data,title=["first", "sec", "3rd"], xticks=xticks, yticks=yticks, reversey=true)
densitymap(data, desnitry, format=Val(:NUMBER), title=["first", "sec", "3rd"], xticks=xticks, yticks=yticks, reversey=true)
densitymap(data, desnitry, format=Val(:DENSITY), title=["first", "sec", "3rd"], xticks=xticks, yticks=yticks, reversey=true)

Use it as you prefer. :)

WHY

Plotting helps you to understand the underlying data. For me I needed to plot relative differences of values, distribution of values in a vector{Float32}, relative differences of matrix values and finally I had to 3-5 times multiple matrix relative differences in the appropriate matrix (Dict{...,Vector{Matrix{Float32}}})... aaaaaand with some frequency number/density "feeling" of the data.

The code is super simple, fork it an use it as you prefer!

Unicode plots should be small and beautiful! :)
