makes a boxandwhisker chart from multiple groups of datasets {data1,data2,}.

Details and Options

  • BoxWhiskerChart draws a box-and-whisker summary of the distribution of values in each datai.
  • 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:
  • dataia pure dataset
    Quantity[datai,unit]data datai with units
    wi[datai,]data datai with wrapper wi
    formi->midata with metadata mi
  • Each datai should be a list of real numbers {y1,y2,}. Elements yj that are not real numbers are taken to be missing and are excluded. If datai 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
    <|k1data1,k2data2,|>association of keys and datasets
    TimeSeries[],EventSeries[],TemporalData[]time series, event series, and temporal data
    WeightedData[],EventData[]augmented datasets
    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,Centerpositions within the box
    Above, Below, Before, Afterpositions outside the box and other elements
    Axison the bar origin axis
    "LowerFence","LowerQuartile","MedianMarker","MeanMarker","UpperQuartile","UpperFence"positions given by box-and-whisker elements
    {{bx,by},{lx,ly}}scaled position {lx,ly} in the label at scaled position {bx,by} for the box-and-whisker elements
  • BoxWhiskerChart has the same options as Graphics, with the following additions and changes:
  • AspectRatio1/GoldenRatiooverall ratio of width to height
    BarOriginBottomwhere to place smallest value for box-and-whisker
    BarSpacingAutomaticfractional spacing between box-and-whiskers
    ChartBaseStyleAutomaticoverall style for box-and-whiskers
    ChartElementFunctionAutomatichow to generate raw graphics for box
    ChartLabelsNonelabels for data elements and datasets
    ChartLegendsNonelegends for data elements and datasets
    ChartStyleAutomaticstyle for box
    FrameTruewhether to draw a frame around the chart
    JoinedFalsewhether to join medians
    LabelingFunctionAutomatichow to label box-and-whisker elements
    LabelingSizeAutomaticmaximum size of callouts and labels
    LegendAppearanceAutomaticoverall appearance of legends
    MethodAutomaticwhat methods to use
    PerformanceGoal$PerformanceGoalaspects of performance to try to optimize
    PlotTheme$PlotThemeoverall theme for the chart
    ScalingFunctionsNonehow to scale individual coordinates
    TargetUnitsAutomaticunits to display in the chart
  • The arguments supplied to ChartElementFunction are the box region {{xmin,xmax},{ymin,ymax}}, the data datai, and metadata {m1,m2,} from each level in a nested list of datasets.
  • A list of built-in settings for ChartElementFunction can be obtained from ChartElementData["BoxWhiskerChart"].
  • 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.

Data and Wrappers  (17)

Single data vector:

Multiple data vectors:

Data vectors in a dataset are grouped together:
