st: RE: RE: multiple barplots wih CIs

["Newson, Roger B" <r.newson@imperial.ac.uk>]

A possible solution might involve the -eclplot- package, downloadable
from SSC using the -ssc- command. -eclplot- has a -supby()- option,
allowing the user to superimpose multiple bar charts with CI whiskers,
separating them by spacing on the X-axis.

I hope this helps.

Hi, 

I think your problem is that rate1 and rate2 may have similar range of
values so they overlapped when both are plotted against groupvar.

One solution is to change the scale of rate1 or rate2 then they can
share
the same x-axis. The other solution is to plot to separate graphs,
saving
them and combine them side-by-side.

I am sorry for being more specific since I am not really clear about
what
you want.

Thuy

Hi folks, 

I've seen earlier listings that demonstrate how to use the twoway option
to
graph CIs upon a barchart for 1 variable, but it all goes pearshaped
when I
try to do the same approach with a second bar/CI combination - the bars
for
the first variable are wide (all bars touching) and the bars for the
second
variable are superimposed upon these, and are narrow.


Incidently, the syntax below also fails to show the lower confidence
value
on the plot. If I flip the order of the rcap and bar statements in the
syntax below, I get an 'invalid syntax' error for the barwidth command.

Does anybody have any ideas on how to fix these errors, in V8.0
intercooled?

Cheers
Dan
