Dear All, I confirm Friedrich observation for my Windows system, and note that: 1) the connect line has a somewhat similar appearance, but steps in one direction only at a lower regular frequency (unrelated to screen pixels). 2) the function line wavers at higher but irregular frequency (also unrelated to pixels). Such appears at all sizes of the graph window. Such in STATA 11 SE, 21st Oct installation and updates, on MS Win XP (ado versions noted below signature line). I would support technical examination of this issue. Geoff. Livesey. Note also: which twoway C:\Program Files\Stata11\ado\base\t\twoway.ado *! version 1.2.0 16apr2007 which scatter C:\Program Files\Stata11\ado\base\s\scatter.ado *! version 1.2.0 16apr2007 which range C:\Program Files\Stata11\ado\base\r\range.ado *! version 2.1.1 13dec1998 -----Original Message----- From: owner-statalist@hsphsun2.harvard.edu [mailto:owner-statalist@hsphsun2.harvard.edu] On Behalf Of Friedrich Huebler Sent: 19 November 2009 16:03 To: statalist@hsphsun2.harvard.edu Subject: Re: st: graphics complaints (Windows too) Dave wrote about Stata on OS X but I have a similar observation about Stata on Windows, specifically concerning -twoway function-. A y=x line drawn with -twoway function- is not as straight as a line drawn with -twoway scatter, connect-. The difference can be illustrated with the following commands. . clear . set obs 2 . gen x = . . replace x = 0 in 1 . replace x = 100 in 2 . gen y = . . replace y = 0 in 1 . replace y = 100 in 2 . twoway (scatter y x, connect(l) clwidth(thin)) (function y=x+1, range(0 100) lwidth(thin)), aspect(1) The -function- line is uneven and can indeed be described as "shocked with electricity", to use Dave's words. Is it possible to draw a -function- line as straight as a -scatter, connect- line?
