(issue1788) Fix area split if there are no NaN's in the data The split algorithmn splits in a way that it always creates at least two datasets. One before the NaN, one after the NaN. This is broken in case the dataset does not contain any NaN value as it resulted in two identical datasets. This changed the display and resulted in a broken area calculation. I've also added some commented out debug code that was helpful tracking down this problem.

#!/usr/bin/env ruby

# Use like
#   grep -ri getLogger src/ | ruby find_alien_loggers.rb
# Prints guesses about java source files where wrong logger is used to stderr.
ARGF.each_line do |line|
  module_name = line.scan(/\/([^\/]*)\.java/)
  next if module_name.nil?
  next if module_name[0].nil?
  module_name = module_name[0][0]
  STDERR.puts line unless line.include?("#{module_name}.class")
end
