1: Linear graph
Linear tables are generally used to describe trends between two sets of data.
Single curve:
s = pd.Series(np.random.normal(size = 50))
s.plot()
Multiple curves:
df = pd.DataFrame({
'one':np.random.normal(size = 20),
'two':np.random.normal(size = 20),
'three':np.random.normal(size = 20)})
df.plot()
