The first thing definitely sounds like an error, I suspect it's just
drawing it on the first one it finds (where "first" is defined somehow).
I'll look into that.
The color is defined by the Slice Color column (near the right) of the
Experiment --> Edit Spectra dialog. (Hmmm, that should now say Trace
Color, I guess, since we now call them that.)
Now with OpenGL, as it happens, the color comes out as specified there,
but with Tk it gets inverted because of the XOR'ing going on. I'm
intending the Tk to be like the OpenGL (on the TODO list).
