New issue 3726 by aka....@gmail.com: plot(Piecewise((x, x > 0), (0, True))) does not work with matplotlib backend
http://code.google.com/p/sympy/issues/detail?id=3726

Here is the complete code:

from sympy import symbols, Piecewise, plot

x = symbols('x', real=True)
plot(Piecewise((x, x > 0), (0, True)))

I get "TypeError: no ordering relation is defined for complex numbers".


Note that if I use text backend, there is no error.  I tried it like this:

from sympy import plot_backends
p = plot(Piecewise((x, x > 0), (0, True)), show=False)
p.backend = plot_backends['text']
p.show()
