Dear Bea,
Please read my previous advise as
ErrorListPlot[{date,
ErrorBar /@ ({xminus, xplus}\[Transpose])}\[Transpose],
PlotStyle -> Red, PlotRange -> Full]
So, /@ instead of @@@ (Map instead of Apply at level 1). The former
yields ErrorBar[{xlow,xhi}], the latter ErrorBar[xlow,xhi] (without
the curly brackets) which is the format for errors in both x and y
directions.
Cheers -- Sjoerd
