analogue to "lines" commant in "plot" when using boxplot

Hello!

I am finding "dotplot" really useful in generating the graph I need. I
was able to make it work for one vector (data series in Excel
language).
However, I want to add the secon line to my graph - based on another
vector (data series).

What command should I use for this purpose in dotplot? I am looking
for a subcommand that would be analogous to the subcommand "lines"
when one is using "plot".

Thanks a lot!
