Problem with volumetric slice plot

[GoogleCodeExporter]

I would like to implement a script for representation of a 4D sample, using 
python language. Then I tested the script of Volumetric Slice Plot shown in 
documentation of Easyviz. The program compiles without wrongs, but the graph 
doesn't appear. I used this script: 



from scitools.std import * 

x, y, z, v = flow()
setp(interactive=False)
h = contourslice(x, y, z, v, seq(1,9), [], [0], linspace(-8,2,10))
axis([0, 10, -3, 3, -3, 3])
daspect([1, 1, 1])
ax = gca()
ax.setp(fgcolor=(1,1,1), bgcolor=(0,0,0))
box('on')
view(3)
show()



What version of the product are you using? On what operating system?
I use Ubuntu 12.4 and the version of python is 2.7.3 

Thak you!!
