ErrorBarFunction

ErrorBarFunction
is an option for ErrorListPlot that specifies a function to apply to determine the shape of error bars.
  • ErrorBarFunction->Automatic generates default error bars.
  • ErrorBarFunction->f specifies that the function f of two arguments is used to generate the error bar.
  • With setting f, the first argument supplied to f is the point around which the error bars are drawn.
  • With setting f, the second argument supplied to f is an ErrorBar object indicating the x and y errors.
Error bars display as intersecting lines by default:
ErrorBarFunction can be used to show error regions as rectangles:
