# Graph the chart data.
|
|
# Input is a 3d matrix that describes a plot that has multiple
|
|
# groups, multiple bars in each group, and multiple values stacked
|
|
# in each bar. The underlying bar() function expects a sequence of
|
|
# bars in the same stack location and same group location, so the
|
|
# organization of the matrix is that the inner most sequence
|
|
# represents one of these bar groups, then those are grouped
|
|
# together to make one full stack of bars in each group, and then
|
|
# the outer most layer describes the groups. Here is an example
|
|
# data set and how it gets plotted as a result.
|
|
#
|
|
# e.g. data = [[[10,11,12], [13,14,15], [16,17,18], [19,20,21]],
|
|
# [[22,23,24], [25,26,27], [28,29,30], [31,32,33]]]
|
|
#
|
|
# will plot like this:
|
|
#
|
|
# 19 31 20 32 21 33
|
|
# 16 28 17 29 18 30
|
|
# 13 25 14 26 15 27
|
|
# 10 22 11 23 12 24
|
|
#
|
|
# Because this arrangement is rather conterintuitive, the rearrange
|
|
# function takes various matricies and arranges them to fit this
|
|
# profile.
|
|
#
|
|
# This code deals with one of the dimensions in the matrix being
|
|
# one wide.
