# how do you make multiple subplots have the same y axis?

I want the data to be comparable

``````import matplotlib.pyplot as plt

dt = {
'2018':[0.31,10.49,39.2,12.58,138.21,94.55,60.97,103.4,95.59,74.85,22.48,6.45],
'2019':[21.6,8.2,5,16.6,177.7,174.1,338.6,216.7,353.3,546.9,138.9,33]
}

x = [i for i, d in enumerate(list(dt.values())[0])]

plt.plot(x, *list(dt.values()))
plt.show()
