profile_id = '...' # Analytics profile ID.

visitors = []
(1..10).each do |i|
  visitors << { x: Time.now.to_i-(10-i), y: 0 }
end

# Get the Google API client
scopes =  ['https://www.googleapis.com/auth/analytics.readonly']
authorization = Google::Auth.get_application_default(scopes)

Analytics = Google::Apis::AnalyticsV3
analytics = Analytics::AnalyticsService.new

# Start the scheduler
SCHEDULER.every '5s', :first_in => 0 do

  # Request a token for our service account
  analytics.authorization = authorization

  # Get the analytics API
  response = analytics.get_realtime_data("ga:" + profile_id, "ga:activeVisitors")
