我正在关注https://www.geekbooks.me/book/view/machine-learning-in-python以制作回归热图。向pcolor热图添加文本标签标签
import pandas as pd
from pandas import DataFrame
import matplotlib.pyplot as plt
headers = ["sex", "length","diameter", "height", "whole_weight", "shucked_weight","viscera_weight","shell_weight","rings"]
下面
迈克尔·鲍尔斯代码:
plt.pcolor(DF_correlation)
plt.show()
这工作得很好,但没有标签的地方,所以我尝试添加标签为matplotlib: colorbars and its text labels
我改变了格式一点点,但还是没有运气:
fig, ax = plt.subplots()
heatmap = ax.pcolor(DF_correlation)
cbar = plt.colorbar(heatmap)
ax.set_xticklabels = ax.set_yticklabels = headers[1:]
plt.show()
如何将标签添加到此图?这是一个相关性图,所以X和Y标签将是相同的...基本上headers[1:]
