Ruby client library

To use the library from within your Ruby script, do as follows:

#require 'charter-client'
# Instantiate a new Charter::Client object:
ch = Charter::Client.new(1)  # 1 is the default ID
# Clear the buffer
ch.clear
200.times do |i|
  # Use the 's' mode:
  # send an array like [x, y1, y2, y3]
  ch << [i/10.0, Math::sin(i/10.0), 1.1*Math::cos(i/10.0), 0.7*Math::sin(i/10.0)+rand*0.05]
end
ch.names %w|speed velocity acceleration|
sleep 5
200.times do |i|
  # alternatively, use the 'm' mode:
  # send an array like [[x1, y1], [x2, y2]]
  ch << [ [i/10.0, rand], [i/10.0+rand*0.01, rand] ]
end
# close the connection, forcing Charter to stop updating the charts:
ch.close
