Re: st: detonator plot with three grouping variables

[David Hoaglin <dchoaglin@gmail.com>]

Ronnie,

A good first step would be to omit the bars entirely.  Freeman et al.
(2008) discuss that type of plot under the name "dynamite plunger
plot" in their chapter "How to display data badly."  The bars take up
space to no good purpose.  A more effective plot would show the
estimates with error bars or confidence intervals (and an explanation
of whether the intervals are error bars or confidence intervals).
