I am a fan of using dot charts as opposed to bar charts (R and S users are familiar with these - it is like a horizontal bar chart only there is a dot plotted where the end of the bar would be,  for an example see www.b-eye-network.com/view/2468).  I figure Maple is flexible enough so that I could program a function to do this but maybe it is already there or someone else has already done this and I just don't know how to find it.
