  4. set obs 50
  5. generate a=runiform()*1000
  6. generate b=runiform()*10
  7. generate s=runiform()<.5

  9. label define sexlab 1 `"{fontface "Female and male symbols":M }"' 0 ///

  11. label values s sexlab

  13. scatter a b , ms(i)  mlab(s) mlabpos(c) ///

  1. *修改后，添加#delimit执行无误
  2. // Circle using function
  3. #delimit ;
  4. twoway (function y = sqrt(1 -(x)^2),
  5. range(-1 1) lwidth(thick) lcolor(red))
  6. (function y = -sqrt(1 - (x)^2),
  7. range(-1 1) lwidth(thick) lcolor(red)), aspect(1);
