IntervalMarkers

IntervalMarkers

is an option for plotting functions such as ListPlot and BarChart that specifies how to represent uncertainty intervals.

Details

  • Interval markers are displayed as follows:
  • IntervalMarkers takes the following forms:
  • Automaticautomatically determined appearance
    Noneignore uncertain data
    "name"use a named appearance to show uncertainty
  • Possible named appearances include:
  • "Bars"draw bars to represent errors
    "Fences"draw fences at the error limits
    "Points"draw points at the error limits
    "Ellipses"draw an ellipse contained in the error limits
    "Bands"draw a band enclosing the uncertainty
  • Possible named appearances in 3D include:
  • "Bars"draw bars to represent errors
    "Tubes"draw tubes to represent errors

Basic Examples  (4)

Visualize the uncertainty around each point:

Wolfram Language code: ListPlot[Table[Around[RandomReal[20], 1], 10], IntervalMarkers -> "Fences"]

Use bars to visualize uncertainty:

Wolfram Language code: ListPlot[Table[Around[RandomReal[20], 1], 10], IntervalMarkers -> "Bars"]

Display a bar chart with uncertainty:

Wolfram Language code: BarChart[Table[Around[RandomReal[5], RandomReal[0.5]], 12]]

Use bands to visualize joined uncertainties:

Wolfram Language code: ListLinePlot[Table[Around[RandomReal[{10, 20}], 1], 10], IntervalMarkers -> "Bands"]

Scope  (4)

Plot data with asymmetric uncertainty intervals:

Wolfram Language code: ListLinePlot[{Around[37., {10., 18.}], Around[48., {6., 17.}], Around[45., {8., 15.}], Around[46., {8., 19.}], Around[53., {5., 11.}], Around[46., {10., 15.}], Around[37., {7., 18.}], Around[57., {7., 20.}], Around[34., {7., 16.}], Around[31., {7., 20.}]}]

Plot correlated uncertainty in 2D:

Wolfram Language code: ListPlot[{VectorAround[{1.8, 2.4}, {{0.3, 0.4}, 0.5}]}, PlotRange -> All, IntervalMarkers -> "Ellipses"]

Plot 3D uncertainty:

Wolfram Language code: ListPointPlot3D[{{0, 0, 0}, {Around[1, 1], Around[1, 1], Around[1, 1]}, {2, 2, 2}, {3, 3, 3}}]

Use tubes to represent uncertainty:

Wolfram Language code: ListPointPlot3D[{{0, 0, 0}, {Around[1, 1], Around[1, 1], Around[1, 1]}, {2, 2, 2}, {3, 3, 3}}, PlotRange -> All, IntervalMarkers -> "Tubes"]

Specify the style to use for uncertainty:

Wolfram Language code: BarChart[Table[Around[RandomReal[5], RandomReal[0.5]], 12], IntervalMarkersStyle -> Red]
