近期绘图较多，在画图的时候总结了一些简单的绘图代码，希望能够帮助大家

Spider Plot绘图代码总结

# Import libs
import pandas as pd
import seaborn as sns
import numpy as np
import matplotlib.pyplot as plt# Get the data
df=pd.read_csv("AwesomeKings.csv")
print(df)"""#             Name  Attack  Defense  Speed  Range  Health

stats=np.concatenate((stats,[stats[0]]))
angles=np.concatenate((angles,[angles[0]]))# Plot stuff
fig = plt.figure()
ax = fig.add_subplot(111, polar=True)
ax.plot(angles, stats, 'o-', linewidth=2)
ax.fill(angles, stats, alpha=0.25)
ax.set_thetagrids(angles * 180/np.pi, labels)
ax.set_title([df.loc[0,"Name"]])
ax.grid(True)plt.show()

树状图代码总结

# Import libs
import pandas as pd
from matplotlib import pyplot as plt
from scipy.cluster import hierarchy
import numpy as np# Read in the dataset
# Drop any fields that are strings
# Only get the first 40 because this dataset is big
df = pd.read_csv('AwesomeKings.csv')
df = df.set_index('Name')
del df.index.name
df = df.drop(["Type 1", "Type 2", "Legendary"], axis=1)
df = df.head(n=40)# Calculate the distance between each sample
Z = hierarchy.linkage(df, 'ward')# Orientation our tree
hierarchy.dendrogram(Z, orientation="left", labels=df.index)plt.show()

热力图代码总结

# Importing libs
import seaborn as sns
import pandas as pd
import numpy as np
import matplotlib.pyplot as plt# Create a random dataset
data = pd.DataFrame(np.random.random((10,6)), columns=["Iron Man","Captain America","Black Widow","Thor","Hulk", "Hawkeye"])print(data)# Plot the heatmap
heatmap_plot = sns.heatmap(data, center=0, cmap='gist_ncar')plt.show()

二维密度图总结

# Importing libs
import seaborn as sns
import matplotlib.pyplot as plt
from scipy.stats import skewnorm# Create the data
speed = skewnorm.rvs(4, size=50)
size = skewnorm.rvs(4, size=50)# Create and shor the 2D Density plot
ax = sns.kdeplot(speed, size, cmap="Reds", shade=False, bw=.15, cbar=True)
ax.set(xlabel='speed', ylabel='size')
plt.show()
