Thank you for the rapid answer, this way it worked for me. However, I have another question as my function involes more terms. The problem occurs also when I do the following:

    var('y')
T = RealDistribution('gaussian',1)
plot3d(lambda x,y:  log(1/(2*pi*x)) + log(T.cum_distribution_function((1-y)/x)), (x,-2,2), (y,-2,2))

While the log() in the second term seems to be no problem, the log() in the first term somehow breaks something, and I get the following long error message:

    TypeError                                 Traceback (most recent call last)
<ipython-input-1-6c109b6281a7> in <module>()
      1 var('y')
      2 T = RealDistribution('gaussian',Integer(1))
----> 3 plot3d(lambda x,y:  log(Integer(1)/(Integer(2)*pi*x)) + log(T.cum_distribution_function((Integer(1)-y)/x)), (x,-Integer(2),Integer(2)), (y,-Integer(2),Integer(2)))
