Flot Rails

Rails 3 Wrapper for flot an ...

Install

Just add the line

gem 'flot-rails', :git => "https://github.com/Kjarrigan/flot-rails.git"

in your Gemfile and run

bundle install

Modify the application.js like shown below:

//= require jquery
//= require jquery.flot
//= require jquery.flot.pie

Then use the pure javascript as shown here: https://github.com/flot/flot/blob/master/API.md or with my little RailsHelper:

module ApplicationHelper
  include Flot
end

<!-- views/my_controller/index.html.erb -->
<%= pie_chart [{label: 'Hello World', data: 50}, {label: 'Foo', data: 25}, {label: 'Bar', data: 25}] %>

If you prefer placing your scripts in header instead of the body, then use something like this:

<!-- views/my_controller/index.html.erb -->
<%= chart(@chart_data, split: true, grid: {hoverable: true}) %>
<%= yield_chart_script_at :flot %>

and append a yield in your layout's head:

<!-- views/layouts/application.html.erb
<head>
  <%= yield :flot %>
</head>
