Thanks to Kit Baum, a new version of the -eclplot- package (described as
below on my website) is available for download on SSC (using the -ssc-
command in Stata 8).
The new version adds an option -eplottype()-, allowing the user a choice of
7 plot types for the estimates, corresponding to the -graph twoway-
subcommands -scatter-, -connected-, -line-, -area-, -bar-, -spike- and
-dropline-. These estimate plot types can be combined with the existing 8
range plot types available for the confidence limits to define 7*8=56
combined plot types, some of which are more useful than others, and all of
which can be either vertical or horizontal. For instance, if the user types
then -eclplot- produces a detonator plot, with the lower confidence limits
visible in front of the bars.
I have also added an option -nociforeground-, allowing the user to specify
whether the confidence intervals are in the foreground or in the
background, relative to the estimates. If not specified, it is set to a
sensible default, depending on the estimate plot type and the confidence
interval plot type. However, in the previous example, the user can override
the default by typing
and produce a detonator plot with the lower confidence intervals invisible
behind the bars, in order to annoy the statistical referee.
The dialog has been updated to allow these new options to be set without
learning a graphics programming language with confusingly-named options,
suboptions and sub-suboptions.
Best wishes

TITLE
eclplot: Horizontal and vertical confidence interval plots
DESCRIPTION/AUTHOR(S)
eclplot creates a plot of estimates with lower and upper confidence
limits
on one axis against another numeric variable on the other axis. The
estimates
and lower and upper confidence limits are stored in three variables,
in a
data set with one observation per confidence interval to be plotted.
Data
sets with such variables may be created manually (using a spreadsheet),
or using the parmest package, or using statsby or postfile in
official Stata.
The user has a choice of plotting the confidence intervals
horizontally or
vertically, a choice of plot styles for the estimates, and a choice
of range
plot styles for the confidence intervals. It is also possible to overlay
the confidence interval plot with other plots using the plot option.
eclplot may be used either as a command or through a dialog.
