# Main features:
# * Stacked bars of 9+ datasets
# * Clustered bars of 8+ datasets
# * Clusters of stacked bars
# * Lets you keep your data in table format, or separated but listed in
# the same file, rather than requiring each dataset to be in a separate file
# * Custom gnuplot command pass-through for fine-grained customization
# without having a separate tool chain step outside the script
# * Color control
# * Font face control and limited font size control
# * Automatic arithmetic or harmonic mean calculation
# * Automatic legend creation
# * Automatic sorting, including sorting into SPEC CPU 2000 integer and
# floating point benchmark groups and sorting by data
#
# Multiple data sets can either be separated by =multi,
# or in a table with =table. Does support incomplete datasets,
# but issues warning.
# For clusters of stacked bars, separate your stacked data for each
# cluster with =multi or place in a table, and separate (and optionally
# name) each cluster with multimulti=
# For complete documentation see
# http://www.burningcutlery.com/derek/bargraph/
#
# This is version 4.8.
# Changes in version 4.8, released January 2, 2017:
# * added datadup= and =datadup_merge for repeated identical values.
# * added colorset= for specifying colors via a list of rgb values.
# * fixed gnuplut 5.0 problems.
# This is version 4.7.
# Changes in version 4.7, released March 25, 2012:
# * added xscale= and yscale= to properly scale graphs on
# gnuplot 4.2+. Note that this may change absolute coordinates
# in existing graphs.
# * switched to boxerror to avoid the data marker for yerrorbars
# * added custfont= feature
# * fixed bugs in centering in-graph legend box
# * added fudging for capital letters to work around gnuplot weirdness
# (issue #15)
# Changes in version 4.6, released January 31, 2010:
# * added automatic legend placement, including automatically
# finding an empty spot inside the graph, via the 'inside',
# 'right', 'top', and 'center' keywords in legendx= and legendy=
# * added logscaley= to support logarithmic y values
# * added leading_space_mul=, intra_space_mul=, and barwidth=
# parameters to control spacing and bar size. as part of this change,
# bars are no longer placed in an integer-based fashion.
# * fixed gnuplot 4.0 regression
# Changes in version 4.5, released January 17, 2010:
# * changed legends to have a white background and border outline
# by default, with legendfill= option (inspired by Kacper
# Wysocki's code) to control the background fill color (and
# whether there is a fill) and =nolegoutline to turn off the
# outline
# * the legend bounding box is now much more accurately calculated
# * eliminated =patterns color with recent gnuplots
# * added legendfontsz= option
# * added =legendinbg option (legend in fg is new default)
# * added =reverseorder option (from Tom Golubev)
# * added =sortdata_ascend option (from Tom Golubev)
# * added =sortdata_descend option (from Tom Golubev)

# * added ylabelshift= option (from Ricardo Nabinger Sanchez)
# * added =stackabs option
# Changes in version 4.3, released June 1, 2008:
# * added errorbar support (from Mohammad Ansari)

# Changes in version 4.2, released May 25, 2007:
# * handle gnuplot 4.2 fig terminal output
# Changes in version 4.1, released April 1, 2007:
# * fixed bug in handling scientific notation
# * fixed negative offset font handling bug
# Changes in version 4.0, released October 16, 2006:
# * added support for clusters of stacked bars
# * added support for font face and size changes
# * added support for negative maximum values
# Changes in version 3.0, released July 15, 2006:
# * added support for spaces and quotes in x-axis labels
# * added support for missing values in table format
# * added support for custom table delimiter
# * added an option to suppress adding of commas
# Changes in version 2.0, released January 21, 2006:
# * added pattern fill support
