A library for making beautiful graphs.
This is beta-quality software. It works well according to our tests, but the API may change and other features will be added. We are working to make Gruff production quality software.
Add this line to your application's Gemfile:
gem 'gruff'
And then execute:
$ bundle
Or install it yourself as:
$ gem install gruff
require 'gruff'
g = Gruff::Line.new
g.title = 'Wow! Look at this!'
g.labels = { 0 => '5/6', 1 => '5/15', 2 => '5/24', 3 => '5/30', 4 => '6/4',
5 => '6/12', 6 => '6/21', 7 => '6/28' }
g.data :Jimmy, [25, 36, 86, 39, 25, 31, 79, 88]
g.data :Charles, [80, 54, 67, 54, 68, 70, 90, 95]
g.data :Julie, [22, 29, 35, 38, 36, 40, 46, 57]
g.data :Jane, [95, 95, 95, 90, 85, 80, 88, 100]
g.data :Philip, [90, 34, 23, 12, 78, 89, 98, 88]
