侧面带有一维切片的Python轮廓图

Question

I want to plot a contour map (using contourf ), but I also want to show on the sides a slice of the plot through particular points, such as the figure shown below.

Answer 1

The plot you show is produced via a seaborn jointplot .

This example shows how to produce the this kind of plot.

import numpy as np
import pandas as pd
import seaborn as sns

# Generate a random correlated bivariate dataset
rs = np.random.RandomState(5)
mean = [0, 0]
cov = [(1, .5), (.5, 1)]
x1, x2 = rs.multivariate_normal(mean, cov, 500).T
x1 = pd.Series(x1, name="$X_1$")
x2 = pd.Series(x2, name="$X_2$")

# Show the joint distribution using kernel density estimation
g = sns.jointplot(x1, x2, kind="kde", size=7, space=0)

import matplotlib.pyplot as plt
plt.show()
