There's probably cleverer ways of doing this ... but why not do the
following? Example bar chart data of first three primes
p = BarChart[Table[Prime[n],{n,3}]]
then use the function
q = ErrorListPlot[{{1,2,0.3},{2,3,0.5},{3,5,1}}]
which generates a plot of data with {x,y,error} where you make sure
that x and y are the tops of your bars in your bar chart. Then just
plot the two together
Show[p,q]
Maybe there is a way of combining ErrorListPlot with BarChart (if
anyone knows?)
