RE: st: Sort order in graph box, over() by()
dear all,
i was just trying to learn from this post with my stata 8.2 but got stuck on
egen axis i.e.:
. egen axis = axis(median rep78), label(rep78)
unrecognized command: _gaxis
r(199);
is there a stata 8.2 equivalent for egen axis = axis(varlists) to show what
nick cox's trying to achieve here?
thank you,
bw

I think Scott's main idea is right. To solve this, you
need to create your own grouping variable upstream of
the graph call.
Here's another way to do it, however, that doesn't
involve resorting to monkeying with extra observations
ad hoc.
sysuse auto, clear
egen median = median(mpg), by(rep)
egen axis = axis(median rep78), label(rep78)
graph box mpg, over(axis) by(foreign, b1title(Repair record 1978))
Here you need to have installed -egenmore- from SSC to get -egen, axis()-.
I have posted on this unofficial -egen- function before, so
here are some related postings:

www.stata.com/statalist/archive/2007-07/msg00563.html

www.stata.com/statalist/archive/2007-08/msg00562.html
If StataCorp would only add one option to -egen, group()-
none of this would be necessary!
I have bundled in the example above an extra trick.
-graph box- won't let you use an -xtitle()-
in this kind of graph because of -graph-'s dogma
that the axis in question isn't an x-axis. A
solution is to invoke -b1title()-.
Those using graphics in Stata <=7 may remember
that graph axis titles came in various flavours,
being -l-, -r-, -b- or -t- according to whether
they were on the left, right, bottom or top.
It doesn't seem to be documented, but some of
the associated options still persist in the new
graphics, chiefly to allow Vince Wiggins a few
extra handles for the very few occasions that he needs them.
