When I need to plot 2 series on y axis, I don’t know if this is the best way. It works with lines, but it does not work with line + bars. If I set y2
kind='bar'
, this serie disappears. indexesM
is my dataframe. This is the code:
x = indexesM.index.to_timestamp() y0 = indexesM['cdi t12m'] y1 = indexesM['ipca t12m'] y2 = indexesM['br real yield t12m'] fig, ax = plt.subplots() ax.plot(x, y0, label='CDI') ax.plot(x, y1, label='IPCA') ax.plot(x, y2, label='Juro real') plt.show()

I created a composite graph by customizing a sample from the official reference. It uses ax.bar()
.
import matplotlib.pyplot as plt data = {'apple': 10, 'orange': 15, 'lemon': 5, 'lime': 20} names = list(data.keys()) values = list(data.values()) fig, ax = plt.subplots(figsize=(9, 3)) ax.bar(names, values, color='g') ax.scatter(names, values, color='r', s=30) ax.plot(names, values, color='b', lw=2) ax.set_title('Categorical Plotting') plt.show()
