```Reg sees a roadblock, then a brick wall. I see no failed code that I can
possibly comment on. I see no precise details on variables.

If method is a variable, -graph box <whatever>, over(method)- is a
recipe.

As Nick says, everything rides on the question whether you want the
graphs
in one panel, or whether they might be -graph combine-d later - in which
case Nick`s suggestion of -if-s and -over-s is back in business...

Reg Jordan

I have measurement values at specified locations over the years 2000 -
2009.
These measurement values were generated using three different analytical
methods. Method 800: 2000 - 2004; Method 802: 2005 - 2007; Method 811:
2000
- 2009. I have been trying to examine the data  for different methods
during
the time periods in which the methods were used. I have tried various
combinations of -if-s and -over-s without success. Hence the SOS.

Nick Cox

Some combination of -if- and -over()- would seem sufficient for either
problem.

Reg Jordan

Thanks so much, Martin. Your suggestion did the trick. Much appreciated.

Martin Weiss

One idea would be to separate beforehand:

*************
sysuse nlswork,clear
separate hours, by(inrange(year, 70,72)) gen(firstsepa) separate hours,
by(inlist(year, 70,73,76)) gen(secondsepa) label variable firstsepa1
`"Variable for Hours in Years 1970-1972"'
label variable  secondsepa1`"Variable for Hours in Years 1970, 1973,
1976"'
graph box firstsepa1 secondsepa1, legend(rows(2))
*************

I have data collected during the years 2000 -2009. I want to boxplot one
of
the data variables, but I've hit a roadblock attempting to plot only
that
variable for certain years.
How would I boxplot data for: (1) years 2000 - 2003, and (2) for years,
say,
2000, 2003, and 2007? Thanks for your assistance.
