Re: st: RE: Different graph height with graph, by()

[Friedrich Huebler <fhuebler@gmail.com>]

Thank you, Scott, this looks very promising. One problem is that there
are large areas between the combined graphs. This is most apparent
when a ysize() option is added to the combined graph, as shown below.
I experimented with graphregion(), plotregion() and imargin() without
success. I also found no information in the documentation for -graph
combine- on how to remove these empty areas.

sysuse auto, clear

local var rep78
levelsof `var',local(levels)

foreach l of local levels {
  qui sum mpg if `var' == `l'
  local a`l' = ceil(r(mean))
  disp `a`l''
  local suma = `suma' + `a`l''
}

foreach l of local levels {
  local grsize`l' = (`a`l''/`suma')*100
  disp `grsize`l''
}

foreach l of local levels {
  graph bar mpg if `var' == `l', ///
    name(gr`l', replace) fysize(`grsize`l'')
  local name "`name' gr`l'"
}

graph combine `name', cols(1) ysize(10)

graph drop `name'
