There is some confusion here. First of all ANSI does not define character sets. (It is a standards organization, but for things like plumbing and electrical fixtures). What you mean is ASCII. If I use - asciiplot- from SSC, it displays the available characters in my current graphics font (set by Preferences->Graphics etc.) Whether I set the default graphics font to Helvetica, Times New Roman or Courier (which are all standard PostScript fonts), ASCII code 178 is \leq and ASCII code 179 is \geq, and something like

local ti "price `=char(178)' 10000"
scatter price mpg if price>=10000,ti("`ti'")

readily displays the \geq symbol in my graph without any PostScript hacking. This works fine on Mac OS X 10.5.5. If you set the current graphics font, doesn't this same technique work on the Dark Side?

for ">=" in the legend text box in a graph. Looking through the
archives, I found Nick Cox's article on inserting awkward characters
in stata which recommended using the 'char' command with the ASCII
codes. This would have worked, but the ASCII code for ">=" comes under
the extended list (code- 242) and this produces a different character
which corresponds to 242 in the ANSI list. It looks like ">=" doesn't
exist in the ANSI list!
