Draws a critical difference graph, which is used to display the
differences in methods' performance. This is inspired by the plots used in:
See Janez Demsar, Statistical Comparisons of Classifiers over
Multiple Data Sets, 7(Jan):1--30, 2006.
Methods are drawn on an axis and connected with a line if their
performance is not significantly different.
:param x: List of average methods' scores.
:type x: list-like
:param insignificant_indices: list of tuples that specify the indices of
all pairs of methods that are not significantly different and should be
connected in the diagram. Each tuple must be sorted, and no duplicate
tuples should be contained in the list.
Examples:
- [(0, 1), (3, 4), (4, 5)] is correct
- [(0, 1), (3, 4), (4, 5), (3,4)] contains a duplicate
- [(4, 3)] contains a non-sorted tuple
If there is a cluster of non-significant differences (e.g. 1=2, 2=3,
1=3), `graph_ranks` will draw just a single link connecting all of them.
Note: the indices returned by this callable should refer to positions in
`scores` after it is sorted in increasing order. It is to avoid confusion
this function raises if `scores` is not sorted.
:param names: List of methods' names.
:param arrow_vgap: vertical space between the arrows that point to method
names. Scale is 0 to 1, fraction of axis
:param link_vgap: vertical space between the lines that connect methods
that are not significantly different. Scale is 0 to 1, fraction of axis size
:param link_voffset: offset from the axis of the links that connect
non-significant methods
