I want to combine a histogram with an xy graph, but the only possibilities are either to combine a bar-graph with a line graph or to combine an xy-graph with y-error bars.

Neither is very good for my purpose, but the latter is the least bad, and I try to improve by chosing the thickest possible line for the error bar. I wonder if it were possible to make those errorbars even broader - perhaps as broad as a histogram bar?
