matplotlib绘图中包括两个概念:figure, axes. 其中figure表示一张图,axes对应一个绘图区域,一个figure中可以包括多个axes, 如下代码: fig = plt.figure()# an empty figure with no Axesfig, ax = plt.subplots()# a figure with a single Axesfig, axs = plt.subplots(2,2)# a figure with a 2x2 gr...

圆环图本质上是一个中间切出一块区域的饼状图。可以使用python和matplotlib库来实现。本文主要介绍基于matplotlib实现圆环图。本文所有代码见:Python-Study-Notes # 去掉警告importwarnings warnings.filterwarnings("ignore")# 多行输出fromIPython.core.interactiveshellimportInteractiveShell ...
