Matplotlib是Python中的一个2D图形包,pyplot里面有很多画图的函数,matplotlib.pyplot包含一系列类似MATLAB中绘制图的函数的相关函数,一般用plt作为matplotlib.pyplot的简写。 一、Matplotlib基础 导包: import matplotlib.pyplot as plt#画图的包 import numpy as np 1. 2. (一)plt.show()函数 在默认的情况在,matplot...
Matplotlib制作图例时报错No handles with labels found to put in legend.解决办法 1.问题现象 报错:No handles with labels found to put inlegend. 2. 解决办法 1)“画图”时未指定label(如下图,没有红框中的内容) 对应的解决办法:添加上即可 2)制作图例在画图之前,则也会报错 对应的解决办法:先plt.plot...

我正在学习DataAnlaysis并与matplotlib.pyplot合作。我正在用Jupyter文件中的matplotlib.pyplot.bar()绘制条形图。我用plt.show()来了解这个数字,但它没有产生任何输出。我试着保存这个数字,它保存的是一个空白图像。 奇怪的是,当我把我所有的代码放在同一个Notebook cell中时。。它起作用了!它保存了图形,并且plt....
