In this earlier post http://jsoftware.com/pipermail/programming/2012-March/027696.html I mentioned some issues with pd and plot in J6.02/Linux.
Today I tried the same examples in J7.01/jhs, in Firefox 11, and observed the same behaviour. In particular, specifying 'aspect 1' does not ensure a 1:1 ratio. ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
