SPSS does not provide this, because one histogram would tend to obscure part or all of the other, but for comparison purposes, there are two things that might be useful.
1. Use a population pyramid (new in SPSS 13). When the variable being charted has a scale measurement level, you get back-to-back histograms, which makes comparisons easy.
2. Use a paneled histogram (also new in 13), which can show two separate histograms, one above the other or as a left-right pair.

Subject: [SPSSX-L] Overlaying Multiple Histograms
I am trying to generate multiple histograms (where one overlays the
other) for a continuous variable, "temp" (range 0-100) where histogram 1
summarizes cases within my dataset where "type" = 1 and histogram 2
summarizes where "type"=2...
Does anyone have any experience in generating such output in SPSS? I
want to avoid using Excel at all costs.
Any help is appreciated. Thanks!
