The trouble with dot plots, as I understand it, is that once a
particular region is saturated with dots, there is no way one can
intuitively estimate the percentage of cells in that region.
It seems to me (and it is quite likely that my friend and colleague Dr.
Roederer will disagree) that dotplots are OK when the region of interest
is one of extremely few events.
I also prefer dot plots with kinetics, because fluctuations in
collection rate can obscure a response of a small population of cells
that rise above the baseline.

You've lost me on this one. Being a relative new-comer to flow
cytometry, I don't see what is wrong with dot plots. Please educate
me. If dot plots are "completely inappropriate", is there ever a
situation when they would be appropriate to use?
