Chartism

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.

Add this line to your application's Gemfile:

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.

mount Chartism::Engine => '/chartism'

An example Linechart Model

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

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:

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