jqplot-rails

Bundled up the latest version of jqplot into something useable with the Rails 3.1 asset pipeline

Usage

include the Gem in your gemfile

gem 'jqplot-rails'

Then include the css and js in your application.{js,css} in your Rails application

application.css:

*= require jqplot

application.js:

//= require jquery
//= require jquery_ujs
//= require jqplot

and optional plugins in application.js:

//= require jqplot/plugins/dateAxisRenderer

after a quick bundle install you should be good to go.

To create a graph in a view, you can use JS or use the following helper

<%= jqplot height, width, data_series, options %>

like in this example

<%= jqplot 200, 400, [[1, 2, 3, 4], [4, 3, 2, 1]], {legend: {show: true}} %>

This helper is based on code from https://github.com/Guidecase/jqplot-rails

Note on Patches/Pull Requests
