plot 重叠使用 matplotlib

Question

I am learning matplotlib.

I am trying to plot two below plots in a single plot using matplotlib.

But it overlaps.

Here is my code.

import matplotlib.pyplot as plt
import pandas as pd
import numpy as np

train_error = [0.26462888486225206, 0.26462383329393313, 0.2628674962680674, 0.2553700231555298, 0.17473717177688022, 0.14773444580059242, 0.1468299949185866, 0.1468235689407127, 0.1439370366766204]
test_error = [0.8438224756653776, 0.8442034650577578, 1.018608707726192, 4.853704454584892, 123.69312582226338, 798.4569874115062, 3205.5264038946007, 9972.587330411312, 10787335.618580218]

plt.plot(train_error)
plt.plot(test_error)
plt.show()

Where am i doing wrong? Can anyone please guide / help ?

Answer 1

Use the subplot

Go check https://matplotlib.org/stable/gallery/subplots_axes_and_figures/subplots_demo.html

plt.subplot(1,2,1)
plt.plot(train_error)
plt.subplot(1,2,2)
plt.plot(test_error)

in plt.subplot(a,b,x) you have a,b that represents the number of (row and column) you want vertically and horizontally and x the index of the subplot selected counting from left to right and top to bottom.
