st: Sequence index plots, subpopuations

[Sonja Bastin <bastinsonja@googlemail.com>]

Hi everyone,

as I have seen in other researcher's work there must be a possibilty to get
well comparable sequence index plots for subpopulations containing differing
numbers of observations.
For example, I want to compare east and west Germans. My sample contains 956
West Germans, whereas only 319 East Germans which means in the left graph
there are 956 sequences displayed, in the right one 319. And as the vertical
axis however is the same for both graphs the images are difficult to
compare. I was thinking about drawing a random sample from all west germans,
containing as many cases as there are east Germans, but with a data set in
sequence format this is not that easy. Of course, I could draw seperate
graphs for both subpopulations and display them in the same size, but this
procedure seems too complicated and not very "fancy". There must be a more
simple solution as graphs of other authors suggest.

Thanks so much for your help
Best
