You could take advantage of python's expansion of positional arguments like
so:
>>> import matplotlib.pyplot as plt
>>> import numpy as np
>>> foo = [np.arange(30), np.random.random((30,))]
>>> plt.plot(*foo)
[<matplotlib.lines.Line2D object at 0x97aef6c>]
>>> plt.show()
The behavior that you describe (plotting many lines) is documented and
expected behavior with a list.
