首先,你需要导入matplotlib的pyplot模块。这是Python中常用的绘图库之一。 python import matplotlib.pyplot as plt 创建图形和坐标轴对象: 使用plt.figure()创建一个图形对象,并使用plt.subplot()创建一个坐标轴对象。如果你不需要创建多个子图,也可以直接使用plt.plot()等函数来绘制图形。 python plt.figure() ax...
import matplotlib.pyplot as plt # We prepare the plot fig = plt.figure(1) # We define a fake subplot that is in fact only the plot. ax = fig.add_subplot(111) # We change the fontsize of minor ticks label ax.tick_params(axis='both', which='major', labelsize=10) ...
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...
我正在尝试动态更新动画matplotlib图表中的条形图值标签。我使用的玩具代码如下: from matplotlib import pyplot as plt from matplotlib import animation import numpy as np fig = plt.figure() x = [1,2,3,4,5] y = [5,7,2,5,3] ax1 = plt.subplot(2, 1, 1) ...
