austin, thanks for your input and clarification.

i tried (FWIW) to get travel.dta but there must an internal check mechanism either at statacorp or my end that blocked its use on my stata 8.2. btw you are right that the [G] i referred to was of stata 8. am not quite sure whether i can get travel.dta with stata 9 (a colleague has it) so that i can see what you are trying to illustrate. conceptually though i think i understand what you are trying to say wrt your example as well as the one on my stata 8 [G] p. 125 and gave me an idea to try.

i tried this:

obs	year	ind_methd	rapid	standard
4	2002	emerg		
5	2002	emerg		
14	2002	rapid	rapid	
1	2003	rapid	rapid	
8	2003	rapid	rapid	
3	2004	emerg		
2	2005	standard		standard
6	2005	rapid	rapid	
10	2005	rapid	rapid	
11	2005	standard		standard
12	2005	standard		standard
7	2006	rapid	rapid	
9	2006	standard		standard
13	2006	rapid	rapid	

then:

. graph bar rapid standard, over(year)
type mismatch
r(109);

. catplot bar rapid standard, over(year)
no observations
r(2000);

BUT:

if i fill the blanks with "." i.e. inserting . (dot or period) to the blank observations in both rapid and standard, i nearly get to where i wanted:

obs	year	ind_methd	rapid	standard
4	2002	emerg	.	.
5	2002	emerg	.	.
14	2002	rapid	rapid	.
1	2003	rapid	rapid	.
8	2003	rapid	rapid	.
3	2004	emerg	.	.
2	2005	standard	.	standard
6	2005	rapid	rapid	.
10	2005	rapid	rapid	.
11	2005	standard	.	standard
12	2005	standard	.	standard
7	2006	rapid	rapid	.
9	2006	standard	.	standard
13	2006	rapid	rapid	.


. graph bar rapid standard, over(year) -> still returns
type mismatch
r(109);

however,

. catplot bar rapid standard, over(year) bargap (-30)

come tantalizingly close to what i wanted if only i can suppress the "." being displayed or used in the resulting graph.

would therefore appreciate further advice/help if possible. otherwise i will settle for:

. catplot bar ind_methd if ind_methd !="emerg", over(year) -> in this case -bargap- option would not be applicable as per austin's explanation.

regards,
bw
