I checked it, and you are absolutely right! BTW, I also tried an IGRAPH,
but I could not find how to change the Y scale to log...
DATA LIST LIST/x y.
/SCATTERPLOT(BIVAR)=x WITH y
* Edit graph & change Y scale to Log (wrong results) *.
COMPUTE logy = LG10(y) .
/SCATTERPLOT(BIVAR)=x WITH logy
* Graph is OK (straight line) *.
(The same code works OK in SPSS 11).
In other recent message to the list I complained about SPSS 12/13
graphing system. I had a collection of templates I used for
meta-analysis (others for survival analysis, regression,
interactions...). Most of them required a change to log scale. When I
tried to update them to SPSS 12, some features could not be applied
anymore, some of them behaved strangely (now I understand), and, I
NEVER NEVER NEVER succeeded trying to apply a chart template using:
I like some SPSS 12 features, like OMS, but I HATE the graphs. I use
SPSS 12 for statistical analyses, but I keep SPSS 11.0 in another
computer for graphing purposes (that's annoying sometimes, because of
incompatibility of output files).

Indeed, the dots >>= 1 are lying on a straight line. But the rest is a
