In order to get that correctly, I think you should sort the lists. You could do it like this:

# List indexes sorted
sorted_list = sorted(range(len(x)), key=lambda a: x[a])

# Based on sorted indexes, sort lists
x = [x[i] for i in sorted_list]
y = [y[i] for i in sorted_list]

# Plot
plt.plot(x,y)
plt.show()

Note that with numpy you could use np.argsort instead of implementing it with list comprehension, and it's probably faster

Yeah that is true. :)
