  * The hash sign ({{{#}}}) is to be interpreted as a comment character in the manner of Python. '''Need some way to declare that a comment is actually a header?'''
  * An arbitrary number of headers may be present on each object. We recommend that these headers are escaped by a prefix {{{#}}} character, for compatibility with gnuplot

 === BAR1D ===
 
+Bar plots are like histograms, but the x axis is discrete. Hence, there is no meaning to the x-spread data, and y-heights should be displayed without a width scaling. Not yet confirmed for use in YODA, but the confusion over histogram height scaling (and the mess of HepData records) suggests that we could do with an explicit type for this.
