About

QuackyCharts is a graphing gem I'm working on. It provides a Ruby syntax for initializing and configuring pie charts and line graphs with D3 and Rickshaw.

Installation

Add this line to your application's Gemfile:

	gem 'quacky-charts'

And then execute:

	$ bundle

Run this command to install the needed JS files:

	$ rails generate quacky:install

Usage

Add this line to the controller:

	@chart = Quacky::PieChartBuilder.new

If you want to add some custom data (otherwise you'll get dummy data):

	@chart.add_data( { "label" => "Category A", "value" => 20 } )
	@chart.add_data( { "label" => "Category B", "value" => 60 } )

and in the view:

	<%= @chart.draw %>

To draw a line graph:

example_data = [{ time: Time.now, data: 50 },{ time: Time.now + 1.hour, data: 75 },{ time: Time.now + 2.hours, data: 25 }]
@line_graph = Quacky::LineGraphBuilder.new(example_data)

and in the view:

<%= @line_graph.draw %>
