利用pandas处理日期数据,并根据日期绘制增长率曲线. 处理的json文本内容如下: # pd.json [{"name": "A", "date": "注册于 2011-6-9"}, {"name": "B", "date": "注册于 2011-6-23"}, {"name": "C", "d…

在进行数据分析时,绘图是必不可少的模式探索方式.用Python进行数据分析时,matplotlib和pandas是最常用到的两个库.1.matplotlib库的应用准备工作如下:打开ipython,输入命令分别导入numpy和matplotlib.pylab库. import numpy as np import matplotlib.pylab as plt 1)创建fig绘图第一步是创建绘图窗口fig. fig1 = plt.figure() 2)创建subplot在窗口上添加AxesSub…

python主流绘图工具:matplotlib ,seaborn,pandas ,openpyxl ,xslwriter openpyxl :首先说下这个官网的demo,看的有点懵,没有具体说明多个图在一个excel引用不通ws Rererence 只是简单的一个deepcopy 用的一点懵逼,反正我是没看懂,其次多sheet写入也未做拓展, 看了下博客哪些水军一篇粘贴复制毫无新意: 下面以openpyxl 3d bar 柱状图为例:演示效果多sheet 生成柱状图: 官网:https://op…
