Any insights? > 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?) David dsmith at psy.ucsd.edu ==== [MESSAGE SEPARATOR] ====
