I tried running this and ran afoul of viewmat and plot. I changed the first
require 'plot graph' to require 'viewmat' I found this rather nice, as the viewmat output was now displayed in-line in the browser. But, non-viewmat plots were a thornier problem. Removing require'plot graph' invoked the new Google plot, which was fine for a few plots, but failed on most with errors like this: unsupported plot options: stick,line unsupported data complexity Changing require'plot graph' to require 'plot' now got what looks like the new GTK plot. This successfully displayed all the plots, but the plot window opened behind my browser window and I had to hunt for it. Also, the plot window appeared before the text in the lab describing the plot. Finally, the plot window had to be closed before I could continue with the lab. And, this would probably would not work well if the J lab browser were not on the same system as jhs. ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
