ErrorBar[yerr]

represents error yerr in both the positive and negative directions.

ErrorBar[xerr,yerr]

represents errors specified for both the x and the y coordinates.

Details and Options

  • To use ErrorBar, you first need to load the ErrorBar Plotting Package using Needs["ErrorBarPlots`"].
  • ErrorBar is used in a list of data points for ErrorListPlot to represent error in a data point.
  • The syntax of a data point, with associated error, is generally {pt,ErrorBar[err]}.
  • The error is expressed as a change in the value at the point.

Examples

Basic Examples  (1)

Wolfram Language code: Needs["ErrorBarPlots`"]

Use ErrorBar to represent errors in a plot:

Wolfram Language code: ErrorListPlot[{{{1, 1}, ErrorBar[0.2, 0.3]}, {{2, 2}, ErrorBar[{-0.5, 1.5}]}, {{3, 4}, ErrorBar[0.3]}, {{4, 6}, ErrorBar[0.4]}, {{5, 7}, ErrorBar[0.8]}, {{6, 10}, ErrorBar[0.5, 1.2]}}, AxesOrigin -> {0, 0}]
