Plotting zero surface does not work

[sylee957]

from sympy import *
from sympy.plotting import plot3d

x = Symbol('x')
y = Symbol('y')
plot3d(0, (x, -1, 1), (y, -1, 1))

It gives an error ValueError: Argument Z must be 2-dimensional. that comes from matplotlib

Hi @sylee957 !

There is a matplotlib function axes3D.plot_trisurf which accepts all the X,Y,Z inputs in 1D which can be implemented in adding some changes in the _process_series function of plot.py.

I would like to work on this. However, I am a bit confused about what the shape of Z is. Could you please help me by expanding a bit more on this issue?

Thank you
