Alas, I got damn few entries in this category. :-(

So, after spending only four solid days researching
the subject I have come up with a method that, while
not exactly straightforward, at least has the advantage
that it can be explained to reasonably intelligent
human beings. At the very least, *I* can understand
it ... sorta. :-)

You can find the explanation (and other recent new
tips to my web page) here:

There is also an example program that you can download
to see how this works. You can find the example program
here:

http://www.dfanning.com/programs/reverse_axes.pro

Note that unlike the RSI example Mark suggested the
other day, these axis titles don't jump all over the
page when the axes are reversed. :-)

One other thing. I've always been mildly annoyed
that the X axis title has appeared closer to its
axis annotation than either the Y axis or the Z axis
titles do. I believe I have discovered the reason for
this, and my method incorporates a "fix" that appears
to correct the problem.

Indeed, you don't have any idea *what* you are going
to learn when you ask one of these simple object
graphics questions. :-)

Cheers,

David
