pxDislin help

[John Fisher]

Hi folks,

I'm having some trouble with the pxDislin module.  I'm unable to get
matrix surfaces to work.  A simple example of my problem:

>>> from pxDislin import *         
>>> from Numeric import *
>>> x = [1,2]  
>>> y = [1,2]
>>> z = reshape(arange(4),(2,2))
>>> sp = dMatrixSurface(x,y,z)
>>> sp.show()
 <<<< Warning   3: Incorrect level in color!   (   0)
 <<<< Warning   3: Incorrect level in survis!   (   0)
 <<<< Warning   3: Incorrect level in surclr!   (   0)
 <<<< Warning   3: Incorrect level in shdmod!   (   0)
 <<<< Warning   3: Incorrect level in surmsh!   (   0)
 <<<< Warning   3: Incorrect level in surfce!   (   0)

I'm sure I'm forgetting something obvious, but I haven't been able to
find any examples of how to use dMatrixSurface in the pxDislin package.

Thanks,
John
