Create 3D points with associated data in Paraview Programmable source

pdo = self.GetOutput()

myPts = vtk.vtkPoints()
myData = vtk.vtkDoubleArray()
myData.SetName("MyData")
myData.SetNumberOfComponents(2)

Nx = 100
Ny = 100

for x in (xrange(Nx)):
	for y in xrange(Ny): 
		myPts.InsertNextPoint(float(x), float(y), 0.0)
		myData.InsertNextTuple2(1.0/(math.sqrt(x**2+y**2)+1), math.sqrt(x**2+y**2))

pdo.SetPoints(myPts)
pdo.GetPointData().SetScalars(myData)

Wonder why the points won't show up on my osx 3.8.0 rc 1. They are there, since you can select them.
