It is certainly possible, but you will have to be
pretty intimate with PLOT keywords. :-)
In particular, you will have to know [XY]STYLE (in
several incarnations, for producing exact axis scaling
and for turning the drawing of some axes off as you
draw others), NOERASE, NODATA, and POSITION to name
just four or five that come immediately to mind.
Then, to draw the squiggle, you will have to use PLOTS.
I've done it, although I no longer have an example of it.
It might take 30 minutes of effort to get it all worked out.
And usually these things are one-offs, so that makes the work
less than satisfying. :-)
Cheers,
David
