笔者用R语言绘制带制图包的定制欧洲地图

一、先看效果：二、安装python：1、下载安装python下载安装python3.9.6，进入python官方网站：//www.python.org/点击Python 3.9.6直接安装即可。2、验证安装成功。按win+R输入cmd，打开控制台，输入python -V，输出python版本号说明安装成功。三、代码##import libraryfrom tkinter import *import timefrom datetime import datetime,time

Python使用Plotly绘图工具，绘制直方图今天我们再来讲解一下Python使用Plotly绘图工具如何绘制直方图使用plotly绘制直方图需要用到graph_objs包中的Histogram函数我们将数据赋值给函数中的x变量，x = data即可绘制出直方图如果将数据赋值给y变量，则会，绘制出水平直方图。下面我们来看个基本例子import plotly as pyimport plotly.graph_objs as goimport numpy as nppyplt = py.o
