"dots" is the closest thing. In fact, they're the same except for the
fact that repeated data points make "circles" bigger. For example, if
your data set is this:
(1,1) (2,2) (1,1)
...then with "dots" there's a dot at (1,1) and one at (2,2); with
"circles" there's a dot (a tiny circle) at (2,2) and a slightly bigger dot
(a slightly bigger circle) at (1,1).
Once you've been collecting data long enough, you might start to see some
real differences, but it depends on what the data set looks like. For
example, our plots are here:
http://www.opendkim.org/stats/graphs/
As you can see, it's mostly dots anyway for the larger signers, and you
would get a good representation of your data just from the dots.
So perhaps the right thing to do is have opendkim-gengraphs auto-sense
which version of gnuplot it has, and select "dots" for things older than
4.4.
