bxp(self, bxpstats, positions=None, widths=None, vert=True, patch_artist=False, shownotches=False, showmeans=False, showcaps=True, showbox=True, showfliers=True, boxprops=None, whiskerprops=None, flierprops=None, medianprops=None, capprops=None, meanprops=None, meanline=False, manage_ticks=True, zorder=None)
Make a box and whisker plot for each column of x or each vector in sequence x. The box extends from the lower to upper quartile values of the data, with a line at the median. The whiskers extend from the box to show the range of the data. Flier points are those past the end of the whiskers.
A list of dictionaries containing stats for each boxplot. Required keys are:
med
: Median (scalar).
q1
, q3
: First & third quartiles (scalars).
whislo
, whishi
: Lower & upper whisker positions (scalars).
Optional keys are:
mean
: Mean (scalar). Needed if showmeans=True
.
fliers
: Data beyond the whiskers (array-like). Needed if showfliers=True
.
cilo
, cihi
: Lower & upper confidence intervals about the median. Needed if shownotches=True
.
label
: Name of the dataset (str). If available, this will be used a tick label for the boxplot
The positions of the boxes. The ticks and limits are automatically set to match the positions.
The widths of the boxes. The default is clip(0.15*(distance between extreme positions), 0.15, 0.5)
.
If :None:None:`True` (default), makes the boxes vertical. If :None:None:`False`, makes horizontal boxes.
If :None:None:`False` produces boxes with the .Line2D
artist. If :None:None:`True` produces boxes with the ~matplotlib.patches.Patch
artist.
Whether to draw the CI notches, the mean value (both default to False), the caps, the box, and the fliers (all three default to True).
Artist properties for the boxes, whiskers, caps, fliers, medians, and means.
If :None:None:`True` (and showmeans is :None:None:`True`), will try to render the mean as a line spanning the full width of the box according to meanprops. Not recommended if shownotches is also True. Otherwise, means will be shown as points.
If True, the tick locations and labels will be adjusted to match the boxplot positions.
The zorder of the resulting boxplot.
A dictionary mapping each component of the boxplot to a list of the .Line2D
instances created. That dictionary has the following keys (assuming vertical boxplots):
boxes
: main bodies of the boxplot showing the quartiles, and the median's confidence intervals if enabled.
medians
: horizontal lines at the median of each box.
whiskers
: vertical lines up to the last non-outlier data.
caps
: horizontal lines at the ends of the whiskers.
fliers
: points representing data beyond the whiskers (fliers).
means
: points or lines representing the means.

Hover to see nodes names; edges to Self not shown, Caped at 50 nodes.
Using a canvas is more power efficient and can get hundred of nodes ; but does not allow hyperlinks; , arrows or text (beyond on hover)
SVG is more flexible but power hungry; and does not scale well to 50 + nodes.
All aboves nodes referred to, (or are referred from) current nodes; Edges from Self to other have been omitted (or all nodes would be connected to the central node "self" which is not useful). Nodes are colored by the library they belong to, and scaled with the number of references pointing them
