tab = Tab() tab.add(showBar(), "笔记本电脑总销量排行榜") tab.add(showPie1(), "MacBook 京东自营店铺销量分析") tab.add(showPie2(), "各品牌4999到10099笔记本销量占比") tab.add(showPie3(), "笔记本电脑全价位各品牌销量占比") tab.add(showBar2(),"好评率从高到低笔记本电脑销量") tab.add(showLine(), "销量Top 10品牌笔记本电脑均价") tab.add(showWordCould(), "品牌词云图") tab.add(showPoint(), "京东各店铺在售品牌") tab.render("JD_phone.html")

这段代码使用了 Python 中的 Tab 和各种图表函数来生成一个包含多个图表的 HTML 页面。具体来说，它创建了一个 Tab 对象，然后使用 add 方法将各个图表添加到该对象中，并为每个图表指定一个标签名。最后，调用 render 方法将 Tab 对象转换为 HTML 页面并保存到本地文件 "JD_phone.html" 中。

以下是美化并转为环形图的代码：

import numpy as np 
import matplotlib.pyplot as plt 
from matplotlib.patches import ConnectionPatch

plt.rcParams['font.sans-serif'] = ['SimHei'] 
plt.rcParams['axes.unicode_minus'] = False 

men_means = (85.5, 91, 72, 59, 66, 55) 
women_means = (94, 82, 89.5, 62, 49, 53) 

ind = np.arange(len(men_means)) 
width = 0.2 

fig, ax = plt.subplots(figsize=(8, 8)) 

ax.bar(ind - width / 2, men_means, width, label='男生平均成绩', color='tab:blue') 
ax.bar(ind + 0.2, women_means, width, label='女生平均成绩', color='tab:orange') 

ax.set_title('高二男生女生各科平均成绩', fontsize=20) 
ax.set_xticks(ind) 
ax.set_xticklabels(['语文', '数学', '英语', '物理', '化学', '生物'], fontsize=15) 
ax.set_ylim(40, 100) 
ax.legend(fontsize=15) 

# 环形图部分
theta = np.linspace(0, 2 * np.pi, len(men_means) + 1)
radii = np.repeat(1.5, len(men_means) + 1)

ax1 = plt.subplot(111, projection='polar')
ax1.plot(theta, radii, color='black', linewidth=1)

for i in range(len(men_means)):
    ax1.fill_between([theta[i], theta[i+1]], 0, radii[i+1], color='tab:blue', alpha=0.6)
    ax1.fill_between([theta[i], theta[i+1]], 0, radii[i], color='tab:orange', alpha=0.6)

    posA = ax1.transData.transform((theta[i], radii[i]))
    posB = ax1.transData.transform((theta[i], radii[i+1]))
    coordsA = ax.transData.inverted().transform(posA)
    coordsB = ax.transData.inverted().transform(posB)

    con = ConnectionPatch(xyA=coordsA, xyB=coordsB, coordsA="data", coordsB="data", lw=1, color='black', alpha=0.8)
    fig.add_artist(con)

plt.tight_layout()
plt.show()

这个代码首先绘制了原始的柱状图，然后使用极坐标系绘制了环形图。环形图中，每个扇形的角度与柱状图中每个柱子对应，颜色则代表男女生的成绩。同时，为了使环形图与柱状图对应，我们使用 ConnectionPatch 将两个部分连接起来。最后，使用 tight_layout() 函数调整布局，使得图像更加美观。

用java写一个底部导航栏+Tab选项卡的代码

以下是使用Java代码实现底部导航栏和Tab选项卡的示例：

import javax.swing.*;
import java.awt.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

public class BottomNavigationBar extends JFrame implements ActionListener {

    private JPanel bottomPanel, tabPanel;

    private JButton homeButton, searchButton, profileButton;

    private JLabel homeLabel, searchLabel, profileLabel;

    private CardLayout cardLayout;

    public BottomNavigationBar() {
        initComponents();
    }

    private void initComponents() {
        setTitle("Bottom Navigation Bar");

        bottomPanel = new JPanel(new BorderLayout());
        tabPanel = new JPanel(new GridLayout(1, 3));

        homeButton = new JButton(new ImageIcon("home.png"));
        searchButton = new JButton(new ImageIcon("search.png"));
        profileButton = new JButton(new ImageIcon("profile.png"));

        homeLabel = new JLabel("Home");
        searchLabel = new JLabel("Search");
        profileLabel = new JLabel("Profile");

        homeButton.addActionListener(this);
        searchButton.addActionListener(this);
        profileButton.addActionListener(this);

        tabPanel.add(homeButton);
        tabPanel.add(searchButton);
        tabPanel.add(profileButton);

        bottomPanel.add(tabPanel, BorderLayout.CENTER);
        bottomPanel.add(homeLabel, BorderLayout.WEST);
        bottomPanel.add(searchLabel, BorderLayout.CENTER);
        bottomPanel.add(profileLabel, BorderLayout.EAST);

        cardLayout = new CardLayout();

        JPanel contentPanel = new JPanel(cardLayout);
        contentPanel.add(new JLabel("Home Screen"), "Home");
        contentPanel.add(new JLabel("Search Screen"), "Search");
        contentPanel.add(new JLabel("Profile Screen"), "Profile");

        add(bottomPanel, BorderLayout.SOUTH);
        add(contentPanel, BorderLayout.CENTER);

        setSize(500, 500);
        setVisible(true);
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    }

    @Override
    public void actionPerformed(ActionEvent e) {
        if (e.getSource() == homeButton) {
            cardLayout.show(tabPanel, "Home");
        } else if (e.getSource() == searchButton) {
            cardLayout.show(tabPanel, "Search");
        } else if (e.getSource() == profileButton) {
            cardLayout.show(tabPanel, "Profile");
        }
    }

    public static void main(String[] args) {
        new BottomNavigationBar();
    }
}

在这个示例中，底部导航栏由三个按钮和标签组成，分别用于在主屏幕，搜索屏幕和个人资料屏幕之间进行切换。CardLayout用于管理不同屏幕之间的切换。当用户点击底部导航栏上的一个按钮时，相应的屏幕将显示在中心面板上。
