# UnicodePlot - Plot your data by Unicode characters

UnicodePlot provides the feature to make charts with Unicode characters.

## Documentation

https://red-data-tools.github.io/unicode_plot.rb/

## Install

```console

$ gem install unicode_plot

```

## Usage

```ruby

require 'unicode_plot'

x = 0.step(3*Math::PI, by: 3*Math::PI / 30)

y_sin = x.map {|xi| Math.sin(xi) }

y_cos = x.map {|xi| Math.cos(xi) }

plot = UnicodePlot.lineplot(x, y_sin, name: "sin(x)", width: 40, height: 10)

UnicodePlot.lineplot!(plot, x, y_cos, name: "cos(x)")

plot.render

```

You can get the results below by running the above script:



## Supported charts

### barplot

```ruby

UnicodePlot.barplot(data: {'foo': 20, 'bar': 50}, title: "Bar").render

```



### boxplot

```ruby

UnicodePlot.boxplot(data: {foo: [1, 3, 5], bar: [3, 5, 7]}, title: "Box").render

```



### densityplot

```ruby

x = Array.new(500) { 20*rand - 10 } + Array.new(500) { 6*rand - 3 }

y = Array.new(1000) { 30*rand - 10 }

UnicodePlot.densityplot(x, y, title: "Density").render

```



### histogram

```ruby

x = Array.new(100) { rand(10) } + Array.new(100) { rand(30) + 10 }

UnicodePlot.histogram(x, title: "Histogram").render

```



### lineplot

See [Usage](#usage) section above.

### scatterplot

```ruby

x = Array.new(50) { rand(20) - 10 }

y = x.map {|xx| xx*rand(30) - 10 }

UnicodePlot.scatterplot(x, y, title: "Scatter").render

```
