Peter, to me (and this is English language) "dot" is shorter than "dash"!
.-.--
dot dash dot dash dash.
So "dot" SHOULD be label for lty="2" pattern: 2 "dots" on, 2 "dots" off
And "dash" SHOULD be label for lty="3" pattern: 3 "dots" on, 3 "dots" off.
Since dot is shorter than dash.

This is answer to previous posting on lwd. So it is there, just not
documented. Thanks.

My comments above were based on viewing saved plot with ghostview and
actually printing it with ghostscript.
