Plot looking really good. A few problems I ran into. First, the demos use several definitions that are created when J6 plot is loaded but not in J7. They are: sin, cos, step and range.
Second, for some reason I don't have ~Demos defined. I defined ~Demos to be 'c:/j701/addons/graphics' but the load still failed. For some reason plotdemos.ijs is in 'c:/js01/addons/graphics/plot/demo', not where the load expects it to be. In addition, I have a directory in bin called '~Demos' which contains a gtk directory. I probably need to start over from scratch reloading all of J; however, the name '~Demos' bothers me. The first letter being capitalized makes me think that it should be defined in UserFolders_j_. But things supplied as part of J should be in SystemFolders_j_ and there should be no assumptions as to the contents of UserFolders_j_.
