Of course they are useful, but do we really need to see them when there are hundreds of samples plotted 1 pixel apart? (As I've said: keep them when when the user "zooms in" on an appropriate small number of samples). But this is an aesthetics-oriented idea, functionality won't be impaired either way so feel free to ignore it. --------------enig25CEE7FDD58BF1678523E18C Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.6 (GNU/Linux) iD8DBQFHmHM1ldnAQVacBcgRAs1mAJ9MMMsBdS1lCroWH7h38ehxRuvu8wCeO/8s 9z35kgXHX0/FW4XGiVHFjhc= =nw4H -----END PGP SIGNATURE----- --------------enig25CEE7FDD58BF1678523E18C--
