I want to make a 3d plot. x is a vector(discrete), y is also a
vector(discrete), for each pairwise x,y I have a value z(x,y)(it is not
a function, just discrete values for each pair of x,y)
I want to show them on a two dimensional plot by showing z(x,y) with
colors.
Thanks for any hint

Those interfaces are long since deprecated. Please use matplotlib instead. http://matplotlib.sf.net

"Long since" being .... When?
I recently installed SciPy and it did not say anything about "deprecated"!

Google for "MayaVi"
It's overkill for what you've described (it doesn't even make 2D graphs
afaik), but it could draw your function as a 3D surface. And besides,
it's way cool.

Only xplt ever got much developer TLC. For the past year or two,
whenever someone comes to the mailing list asking about some problem
with {x,g,wx}plt, we've been referring them to matplotlib. During the
transition to the new scipy_core, all of them have been moved to the
sandbox/ directory and won't be returning. If you're using xplt, some
people mentioned that they might be interested in maintaining it, but it
will have to be forked off into it's own project.

For such things, I like R (from http://www.rproject.org), for which
also exist a few Python interfaces (I use http://rpy.sourceforge.net).
For communication between Python and R, Python Numeric facilities are
usable, yet not required. Moreover, with 3Daccelerated cards or
simulations thereof, OpenGL tools (see http://rgl.neoscientists.org)
allow you to interactively wander into your plot, somehow.
The combination is worth. What may appear as a drawback is the need to
become acquainted with R, the system and the language. But if you
happen to do scientific works, this really is a worth investment.
