I'm stuck again. This time it has to do with plotting using "pd" commands. Here's some data and some demo code:
------------------------------------------------------------- load 'plot' ary4=. 19 29 47 57 63 76 86 97 104 108 ary4a=. 6 4 6 4 6 4 6 4 6 4 pd 'reset' pd 'yrange 0 10' pd 'xrange 0 ', ": <:120 pd 'xtic ', ": <:#ary4 pd 'xticpos ', > ": each ary4 NB. xticpos pos1 pos2 pos3... pd ary4a pd 'show' ------------------------------------------------------------- If you omit the "xticpos" line, you will at least get a visible plot display--although it's incorrect. Include the "xticpos" line, and you get the following error message: |option not found: 19: signal | signal'option not found: ',j No matter what I've tried, I can't seem to get the "xticpos" command to work correctly. Help, please. Many thanks in advance! Harvey ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
