Try this: import numpy as np import matplotlib.pyplot as plt salinity = np.random.random(50) depth = np.linspace(1, 500) plt.plot(salinity, depth) ax = plt.gca() ax.set_ylim(500, 0) Things to note: 1) Matplotlib doesn't care about dependent or independent variables. With plot(x,y), one variable gets mapped to the x-axis, one gets mapped to the y-axis. 2)ax.set_ylim says that the call is (min,max), but what it really means is (lower,upper). This could probably be clearer in the docs.
