Plot expects the "x" values as the "positions" component and the "y" values
as the "data" component. So first you need to get it structured that way.
ImportSpreadsheet will import it as two components, called by default
"column0" and "column1" (I think).  You should be able to just use Rename
to rename them to the right component names. Use the Print module to see
how they are imported. Alternatively you could add the component names as
the first line of the imported data file; ImprortSpreadsheet will use those
names as the component names.

Another possible gotcha is that if your data is as below the positions will
be imported as integers, while DX needs floats, so you'll need a cast
first. I've attached a net, as this is probably seeming rather complex.
Which perhaps it is, but DX really isn't a plotting package. If what you're
mostly interested in doing is plotting lines, DX is probably not the right
tool. It's plotting capabilities are fairly rudimentary; it's really
intended for 3D visualization. Understanding the way in which DX creates
geometry from data is pretty important to making all this seem less
arbitrary (which it really isn't).

Please pardon my ignorance, but can someone
tell me how to simply phi vs x on a simple "plot"
given that I have a flat file with x in one column, phi in another
as such:

2160   3.456
2161   3.455
2162   3.454
2163   3.453
etc...

I'm trying to use an "ImportSpreadsheet"
and then a "plot" object into an image,
but something is missing.

Russ
