Unfortunately, the only routine I had to drop into our local plotting package was written in Fortran with almost no comments. I was able to hack it up enough to make it work with our local devices...but it is a long way from perfect. Does anybody have a nice C routine that does hidden line plots? It would be best if it was documented, but I'll take anything. I wouldn't even mind Fortran, if the program was documented. I'll be happy to send out what ever I get to anybody that requests it. Thanks for your help. Malcolm Slaney Purdue EE Dept. {decvax,inuxc,ih*,ucbvax, teklabs}!pur-ee!malcolm
