In [9]: %matplotlib qt
   ...: from sympy import *
   ...: 
   ...: x = symbols('x')
   ...: plot(4-x**3/2, x*x, (x, 0, 2), legend=1)

As you can see, I can plot two curves and Sympy takes care of labelling them, but.

I want to label the first curve “cubic” and the second one “quadratic”, but I don’t kmow how to specify two labels, I tried with label=['c', 'q'] but Sympy displayed "['c', 'q']" twice…

How can I set a distinct label for each curve?
