DESCRIPTION

ruby-googlechart is a ruby library which provides object-oriented access to the Google Charts API.

This library has largely been done as an exercise. These other ruby libraries are more mature and may be better suited to your needs:

• googlecharts.rubyforge.org/
• code.google.com/p/gchartrb/

FEATURES

• Line charts (line, XY, sparkline)
• Bar charts (horizontal, vertical, grouped, stacked)

SYNOPSIS

  require 'google_chart'

  url = GoogleChart.Line(:data => [1, nil, 2, 8, 1])
  url = GoogleChart.Bar(:data => [5, 23, 6, 14])

  url = GoogleChart.Bar do |c|
    c.axes     = {:x => %w[Q1 Q2 Q3 Q4], :y => 0..400}
    c.data     = [335, 285, 240, 220, 160, 175, 200, 205]
    c.encoding = :extended
    c.scale    = 0..400
    c.size     = '800x375'
    c.style    = :dash
    c.title    = "Are You Pondering What I'm Pondering?"
    c.type     = :line
  end
  url = GoogleChart.Bar do |c|
    c.horizontal = true
    c.grouped    = true
    c.data       = [[5, 6, 7, 8], [23, 14, 17, 16]]
    c.encoding   = :text
    c.title      = 'Lorem Ipsum Dolor'
  end

  chart = GoogleChart::LineChart.new
