I am using Isosurface to create contours on a map, and I have a set of categories which I am mapping individually. When I autogrid the data and use Isosurface to create the contours, on some of the maps a series of straight horizontal lines appear which makes it seem that the contours are running off the image. Sometimes there are many, sometimes there are few, and sometimes the image looks normal. Has anyone ever encountered this before, and if so, how does one fix it?
Thank you, Mike Rizzo
