A different thought: a -subtitle()- in the top left could serve the same purpose as a textbox. Also, the -subtitle()- can also be moved inside the data region.

It is clear why you want to subvert that, but Stata's algorithms are a little complicated, given explicit and implicit requests for axis scales together with label and tick positions. > > That said, if you are not using the -legend()- option, this is a different technique: > > . sysuse auto > (1978 Automobile Data) > > . scatter mpg weight, legend(on order(- "text here") pos(11) ring(0)) > > Although it's not documented as such in recent manuals, as far as I can recall, this article is still of some relevance > > STB-25 dm28 . . .

While it explains some of Stata's behavior, it doesn't explain the "choose-a-nice-number routine" (Stata's words, see -help axis_label_options-) which I believe is what I'm after.

However, because Stata chooses the x and y ranges to be neat, there's no way for me to know exactly what the minimum x value & maximum y value are. If I simply choose these values from my data, the text box is always closer to the center than I'd like. >> >> Is there a way to obtain this information from Stata? Alternatively, is there an option to place the textbox in the upper left? * * For searches and help try: * http://www.stata.com/help.cgi?search * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/
