# Gruff::AccumulatorBar is a special bar graph that shows a
# single dataset as a set of stacked bars.
# The bottom bar shows the running total and the top bar shows
# the new value being added to the array.
#
# Here's how to set up a Gruff::AccumulatorBar.
#
# g = Gruff::AccumulatorBar.new
# g.title = 'Your Savings'
# g.data 'First', [1, 1, 1]
# g.write('accumulator_bar.png')
