You might have luck constructing a 2D array, where one axis is time
and one is altitude. Then you would go through and fill the measured
values into the array, and finally use an image displayer like
PLOTIMAGE or IMDISP to render the image with a coordinate system.
Another possibility is to PLOT your coordinate axes first, and then
overlay small image stripes for each measurement. You could use
something like OPLOTIMAGE for this. Then perhaps at the end, you will
need to re-render the coordinate axes in case some axis marks were
obscured.
Good luck,
Craig
P.S. O/PLOTIMAGE can be found at:

and IMDISP is by Liam Gumley and available at:
