BUILT-IN MATHEMATICA SYMBOL
BoxWhiskerChart
BoxWhiskerChart[{x1, x2, ...}]
makes a box-and-whisker chart for the values 
.
BoxWhiskerChart[{x1, x2, ...}, bwspec]
makes a chart with box-and-whisker symbol specification bwspec.
BoxWhiskerChart[{data1, data2, ...}, ...]
makes a chart with box-and-whisker symbol for each 
.
BoxWhiskerChart[{{data1, data2, ...}, ...}, ...]
makes a box-and-whisker chart from multiple groups of datasets 
.
- BoxWhiskerChart draws a box-and-whisker summary of the distribution of values in each
.
- The following box-and-whisker specifications bwspec can be given:
-
| "Notched" | median confidence interval notch |
| "Outliers" | outlier markers |
| "Median" | median marker |
| "Basic" | box-and-whisker only |
| "Mean" | mean marker |
| "Diamond" | mean confidence interval diamond |
| {{elem1,val11,...},...} | box-and-whisker element specification |
| {"name",{elem1,val11,...},...} | named bwspec with element modifications |
-
- The elements and values include:
-
| {"Fences",width,style} | width and style of fences |
| {"MeanDiamond",width,style} | width and style of mean confidence interval |
| {"MeanMarker",width,style} | width and style of mean marker line |
| {"MedianNotch",width,style} | width and style of median confidence interval |
| {"MedianMarker",width,style} | width and style of median marker line |
| {"Outliers",marker,style} | marker symbol and style for outliers |
| {"FarOutliers",marker,style} | marker symbol and style for far outliers |
| {"Whiskers",style} | style for whiskers |
- The width is given as a fraction of the width of the box, and the marker can be any expression.
- Data elements for BoxWhiskerChart can be given in the following forms:
-
| datai | a pure dataset |
| wi[datai,...] | data  with wrapper  |
| formi->mi | data with metadata  |
- Each
should be a list of real numbers 
. Elements 
that are not real numbers are taken to be missing and are excluded. If 
is not a list of real numbers, it is taken to be missing data and will typically result in the gap in the box-and-whisker chart.
- Datasets for BoxWhiskerChart can be given in the following forms:
-
| {data1,data2,...} | list of elements with or without wrappers |
| w[{data1,data2,...},...] | wrapper applied to a grouped dataset |
| w[{{data1,data1,...},...},...] | wrapper applied to all grouped datasets |
- Possible symbolic wrappers are the same as for BarChart and include Style, Labeled, Legended, etc.
- In BoxWhiskerChart, Labeled and Placed allow the following positions:
-
| Top,Bottom,Left,Right,Center | positions within the box |
| Above, Below, Before, After | positions outside the box and other elements |
| Axis | on the bar origin axis |
| "LowerFence","LowerQuartile","MedianMarker","MeanMarker","UpperQuartile","UpperFence" | positions given by box-and-whisker elements |
| {{bx,by},{lx,ly}} | scaled position  in the label at scaled position  for the box-and-whisker elements |
- BoxWhiskerChart has the same options as Graphics, with the following additions and changes:
-
- The arguments supplied to ChartElementFunction are the box region
, the data 
, and metadata 
from each level in a nested list of datasets.
- A list of built-in settings for ChartElementFunction can be obtained from
.
- With ScalingFunctions->s, the data coordinate is scaled using s.
- Style and other specifications from options and other constructs in BoxWhiskerChart are effectively applied in the order ChartStyle, Style and other wrappers, and ChartElementFunction, with later specifications overriding earlier ones.
Generate a box-and-whisker chart for a data vector:
| Out[1]= |  |
Generate a box-and-whisker chart for a list of data vectors:
| Out[2]= |  |
Chart several collections of datasets:
| Out[2]= |  |
Customize the appearance of the box-and-whisker chart:
| Out[2]= |  |
Show outliers:
| Out[3]= |  |
Use categorical labels:
| Out[2]= |  |
Categorical legends:
| Out[3]= |  |
Show outliers:
| Out[2]= |  |
Show notches for the median confidence interval:
| Out[3]= |  |
