Add Vertical Reference Line to a Histogram

Does anyone know how to add a vertical line onto a histogram.  I'd like to have a second series (function) on my graph that shows the average (and standard deviation +-1 from the mean).  I can get the graph to plot the average of the histrgram count (a horizontal line over the histogram), by adding a "New Function"  but I can't figure out how to plot a vertical line over this histogram.
