  I appended a single arbitrary value for limits  
  since the  limits  list had not been previously
  initialized .... 
  
  ....

  colourofbars = [ ]

  for key , value in dict_means.items() :

      limits.append( 3000 )

      if limits[ 0 ] > ( key + ( value ) ) :
  ....

  This fix gets past the  index out of range  error
  and produces a plot which might let you proceed
