Hi ... I wonder if anybody out there has experience with DP Graph. It's a cool graphing program and almost free, but very techy and not much documentation.

I know how to graph a vector field, and I know how to graph a single vector using the "near" function. But how do I graph two vectors, or three, in the same 3D box? Everything I try gets me a "syntax error," with no help in finding out where my error is.
