Here's what I'm working with:
<img src = "http://www.calpoly.edu/~bborra/phys417.png" />
I used:
<blockquote>plot3(...)
...
v = axis
...
text(v(2),0,v(5),'Y = 0')
</blockquote>
Is this possible?
Possibly if you used bitmapped text texture-mapped on to a surface with
alpha set to 0 where-ever the text is absent.
