This library is designed for making charts with ease. It provides a clean DSL to describe charts.
It is base on the great chartist.js library.

## Installation

Add this line to your application's Gemfile:

```ruby
gem 'chartism'
```

And then execute:

    $ bundle

Or install it yourself as:

    $ gem install chartism

Add to your `application.js`

```
//= require chartism
```

And add to your `application.css`

```
*= require chartist.min
```

Finally, mount the engine in your routes file.

```ruby
mount Chartism::Engine => '/chartism'
```

## Usage

An example Linechart Model

```ruby
Chartism.line_chart :a_line_chart do
  options do
    points false
    smooth false
    area true
  end

  labels do
    %w(Mon Tue Wed Thu Fri)
  end

  series do
    [5, 2, 4, 2, 0]
  end

  series do
    [6, 3, 1, 2, 4]
  end
end
```

An example pie chart

```ruby
Chartism.pie_chart :a_pie_chart do
  options do
    donut true
    width 80
  end

  labels do
    %w(Mon Tue Wed Thu Fri)
  end

  series do
    [5, 2, 4, 2, 7]
  end
end
```

Then use the following in a view:

```erb
<%= chart :a_line_chart, class: ['ct-perfect-fourth'] %>
```
