Lets just be realistic: IDL object graphics is a pretty toy, which might be
useful for drawing scenes etc, but for real scientific data it's the
proverbial heap of donkey dung. I would not like to try to write (for
example) a routine to time label an arbitrary axis which might be anything
from 2 minutes to 20 years in length with object graphics. [Anyone who wants
to see how its done in direct graphics (well; up to 10 years the externsion
to 25 hasn't been released yet) should go to:
