Hi,
I think it can be done by applying a Calculatur filter first to store the
coordinates as an additional point dataset (named e.g. 'xyz'), then applying the
original Plot over Line filter and finally a Programmable Filter with the
following code:
inp = self.GetInput()
filename = "foo.csv"
FILE = open(filename,"w")
FILE.write("x,y,z, x-velocity")
numPoints = inp.GetNumberOfPoints()
coords = inp.GetPointData().GetArray("xyz")
vel = inp.GetPointData().GetArray("Velocity")
for i in xrange(0, 3*numPoints, 3):
FILE.write(str(coords.GetValue(i)) + "," + str(coords.GetValue(i+1)) + "," +
str(coords.GetValue(i+2)) + "," + str(vel.GetValue(i)))
FILE.close()
(write statement is one big line, despite it being wrapped in this message)
