Nick,

thanks a lot for your response.

I would like to plot my data in a mean + confidence
interval way (Stata 8).
This can be nicely done with -ciplot-.
My question:
I would prefer to have the mean represented by a bar
instead of a dot,
starting from zero, just like this:

   ^
   |        ---
   |         |
   |         |
   |         |
   |     XXXX|XXXX
   |     XXXX|XXXX
   |     XXXX|XXXX
   |     XXXX|XXXX
   |     XXX---XXX
   |     XXXXXXXXX
   |     XXXXXXXXX
   |     XXXXXXXXX
   |     XXXXXXXXX
   |     XXXXXXXXX
   ---------------------->


Is it possible to draw such a graph in Stata 8?




This topic has been discussed several times on Statalist
over the last few months. Possibly no topic has engendered
such passionate exchanges on Statalist in 2003.


[...]



In particular, I posted some code on Statalist on 30 June,
building on a suggestion by Stephen McKay. I didn't get
any comments, public or private, on whether it was
quite what people wanted.


I am sorry if I invested too few effort browsing the archives before
posting on statalist, and I actually missed the message you are referring
to.

(For those who are interested:
http://www.stata.com/statalist/archive/2003-06/msg00631.html)

I tried your code, and it worked like a charm, producing exactly what I
need. Thank you very much for the code.




It shouldn't be too difficult to write a version of
-ciplot- to do confidence intervals shown as these bar on bar
plots, but I await expressions of interest in using that
program before I actually write it.


Adding a bar on bar feature to -ciplot- would be a wonderful and very
useful extension in my opinion, and I hope others think the same.

Again, thanks a lot for your help.
Best regards,
Eva Poen
