Have you considered the error bar or dropline charts in Statistics? They
default to vertical lines, but that is easy to reverse.

Thank you. Those are those are the kinds of graphs I had in mind,
Since R can be called from SPSS, do you have SPSS syntax to do this task?

Everyone:
The dotchart() function in R will accommodate this action fairly easily if
you can not find a SPSS fix.
A simple set of R syntax (about baseball, of course!) follows:
On1stBase <- c(3,4,1,2,4,2,3,6,1,0,
+ 6,3,3,5,2,1,3,7,1,3,
+ 5,3)
On1stBase
[1] 3 4 1 2 4 2 3 6 1 0 6 3 3 5 2 1 3 7 1 3 5 3
par(ask=TRUE)
dotchart(On1stBase,
+ main="Dotchart of On1stBase",
+ xlab="On1stBase",
+ font.lab=2,
+ col="red")
Waiting to confirm page change...
Going beyond this simple example, look at
http://polisci.msu.edu/jacoby/research/dotplots/tpm/Jacoby,%20Dotplots,%20TPM%20Draft.pdf
and give attention to Figure 4 (R syntax begin on p. 11 and Figure 4 is on
the last page of this document).
Best wishes.
