可视化-vscode安装matplotlib工具
作者：互联网
可视化工具中，最流行的工具之一是 Matplotlib，它是一个数学绘图库，可以制作简单的图表，如折线图和散点图；
使用pip可以安装Matplotlib；
安装步骤：：
1、在vscode的终端输入命令： py -m pip install --upgrade pip # 先更新pip版本
PS D:\01VSCodeScript\Python> python.exe -m pip install --upgrade pip
Requirement already satisfied: pip in c:\users\12593\appdata\local\programs\python\python310\lib\site-packages (22.0.4)

2、安装matplotlib；

3、检查路径
因为出现告警：
Import "matplotlib.pyplot" could not be resolved from source
可能是路径不对，
查看安装的模块；
PS D:\01VSCodeScript\Python> pip list Package Version --------------- ------- autopep8 1.6.0 cycler 0.11.0 fonttools 4.33.3 kiwisolver 1.4.3 matplotlib 3.5.2 numpy 1.23.0 packaging 21.3 Pillow 9.2.0 pip 22.1.2 pycodestyle 2.8.0 pygame 2.1.2 pyparsing 3.0.9 python-dateutil 2.8.2 setuptools 58.1.0 six 1.16.0 toml 0.10.2 PS D:\01VSCodeScript\Python>
在终端中输入，检查路径
PS D:\01VSCodeScript\Python> pip show matplotlib Name: matplotlib Version: 3.5.2 Summary: Python plotting package Home-page: https://matplotlib.org Author: John D. Hunter, Michael Droettboom Author-email: matplotlib-users@python.org License: PSF Location: c:\users\12593\appdata\roaming\python\python310\site-packages Requires: cycler, fonttools, kiwisolver, numpy, packaging, pillow, pyparsing, python-dateutil Required-by: PS D:\01VSCodeScript\Python>
在搜索中输入：python.analysis.extraPaths
重新运行后，没有出现告警了
4、简单测试，python脚本:
import matplotlib.pyplot as plt squares = [1, 4, 9, 16, 25] # 调用函数subplots,在一张图片中绘制一个或多个图表； # fig，表示整张图片 # ax，表示图片中的各个图表 fig, ax = plt.subplots() # 调用plot()方法，尝试根据给定的数据以有意义的方式绘制图表 ax.plot(squares) # 函数plt.show()，打开Matplotlib查看并显示绘制的图表 plt.show()
