The option text (#y #x "text") does work with -graph bar- (check page 118, graphics manual). Stata interprets the number #y in the units used on the y-axis. The manual says the number #x is to be in the range 0-100, and I suppose this is a percentage of the width of the graph. Perhaps Dr. Wolfram did not notice this because the various x values he tried may not have been sufficiently different to produce a noticable effect on his graph. The point to note here is that -text()- works differently with -graph bar- that with -twoway- because, as Nick Cox pointed out, -graph bar- does not have an x-axis. On graphs which do have an x-axis, the number #x in -text(#y #x "text")- is interpreted by Stata in the units used on the x-axis (see page 19, graphics manual). The following example may be helpful: . sysuse educ99gdp . drop if _n>6 . graph bar (asis) public private, over(country) text(0.8 10 "text") . graph bar (asis) public private, over(country) text(1.25 90 "text") -- May mboggess@stata.com * * For searches and help try: * http://www.stata.com/support/faqs/res/findit.html * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/
