I gutted one of my do-hickeys for the
plotting core to help 'youse guys in drawing particular segments.
This is set up for a black background and EOD
data.
Change 'BC' to your screen background
color.
Use Parameters to adjust the Span and Offset of
the lines.
Change 'Y' to whatever you want to
track.
I included examples of lines above and below,
dashed lines, finding line spacing, and etc. (ad nauseum).
Obviously, if you extend the lines off the edge of
the screen, things get screwy. So don't. You were warned. It will cost $1500 to
explain why.
