I did some more work on "nice numbers" on logarithmic scales about a
year ago, but I need to go back and finish it.
A more systematic approach to a related (but not identical) problem is

P.S. I didn't know (or had forgotten) about Rense Corten's blog. He
comments that Statalist "is so busy that it is close to worthless if
you are not looking for something specific".

2) I discovered a very useful piece of code to have the labels of a log
plot
display powers of 10.
It is on Rense Corten's blog (comments off):
http://www.rensecorten.dds.nl/index.php/2011/03/labeling-logarithmic-axes-in-stata-graphs/
It's similar to something you wrote on Statalist back in 2003:
http://www.stata.com/statalist/archive/2003-11/msg00770.html
I adapted it to make it a little more systematic, e.g. writing:
forval x = `expmin'(`expstp')`expmax'{
instead of say
forval x = 2(1)5{
and I have set up some calculations beforehand decide what the values of
expmin, expstp, expmax should be, based on the data being graphed.
The whole thing could be wrapped into a program (by someone more able
than
me).
I hesitate to post my version of the code since the original was not
written
by me.
There isn't an awful lot I can give back to Statalist now, but hopefully
some day...
Thanks Nick.

Here is an example.
sysuse sp500, clear
histogram close, horizontal xsc(reverse) normal freq ysc(off)
fxsize(20) name(g1, replace) width(10)
line close date, ysc(alt) yla(, ang(h)) name(g2, replace) xla(,
format(%tddd_Mon)) xtitle("2001")
graph combine g1 g2, ycommon imargin(small)
However, this example does not imply that I just wrote down these
commands. No; this is the cleaned-up version after making numerous
small changes. Open a do-file editor with a script once you have
commands that work, expect to have to make many tweaks. -name(,
replace)- is a crucial detail.

See -help graph combine- and then the manual entry. In Stata terms,
you combine using graphs from -twoway histogram- and -twoway line-.

I saw this very nice graph: the main graph area has a twoway line of
some
very spiky data, in a standard horizontal orientation; immediately
next
to
it, on the left-hand side, is a frequency plot displayed sideways.
Does anyone have sample code for this sort of display?
many thanks.
