Roger Newson <r.newson@imperial.ac.uk> asks, > A minor query re Stata 9 and 10 graphics. Is there any special > reason why the -plot()- option of Stata 8 was renamed to the > -addplot()- option in Stata 9? I admit that I don't recall. A few possibilities are: o We thought the name -plot- was too ambiguous given that the documentation for -twoway- relies so heavily on the concept of plots. o We thought that the option name -plot- might be extremely useful for a different purpose in the future. (And I don't know what that would be.) o We wanted to emphasize that you were adding a plot, and not designating what was plotted. I will also admit that none of those reasons sounds right. Given that we try very hard not to change existing names without truly good cause, I am pretty sure the real reason was more compelling than those listed above. The intervening years have not been kind to that particular memory. Roger goes on to ask, > And is the name now stable? (It seems to have persisted in Stata > 10.)

Roger need not worry. It is highly unlikely we will decide to rename this option yet again. Any perusal of the historical stability of Stata command syntax and option names will support that conclusion. Even if, against all my assurances, we did decide to rename the option in the future, the name -addplot- is not very interesting for other uses, and so while it might go undocumented, it would continue to work. -- Vince vwiggins@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/
