本文使用python中的itchat模組獲取微信資訊，並用matlab進行資料顯示，這兩個模組沒有的可直接在控制檯 pip install ** 進行安裝，話不多說，先上效果圖

一、男女比例分析

二、各個地區的男女數量-柱狀圖

三、各個地區的男女數量-橫向柱狀圖（地區標籤比較清晰）

下來一 一上程式碼，做這個主要還是看資料怎麼分析，以及運用下圖表的顯示方式，matlab挺強大的，支援一下

一，餅狀圖程式碼

import itchat, time
import matplotlib.pyplot as plot

def chatProportion():
    itchat.auto_login(True)
    male = female = other = 0
    rName = "群名稱，自己填"
    roomSum = 0
    chatRooms = itchat.search_chatrooms(name=rName)
    if chatRooms is None:
        print("no this:" + rName)
    else:
        chatRoom = itchat.update_chatroom(chatRooms[0]['UserName'], detailedMember=True)
        index = 0
        mem_list = chatRoom['MemberList']
        roomSum = len(mem_list)
        for friend in mem_list:
            dis = friend['DisplayName']
            nick = friend['NickName']
            sex = friend['Sex']
            if sex == 1:
                male += 1
            elif sex == 2:
                female += 1
            else:
                other += 1
            index += 1
            print(index,dis,nick,sex)
    labels = ['男:'+str(male),'女'+str(female),'其他'+str(other)]
    sizes = [male, female, other]
    colors = ['green','red','gray']
    # 幾個分量向外偏移
    explode = (0.1,0.1,0)
    plot.pie(sizes,explode,labels,colors,'%2.0f%%')
    plot.axis('equal')
    plot.legend(loc='upper left', bbox_to_anchor=(-0.1, 1))
    plot.rcParams['font.sans-serif'] = ['Microsoft YaHei']
    plot.rcParams['axes.unicode_minus'] = False
    plot.title("群名："+str(rName)+"[總人數："+str(roomSum)+"]\n"+str("(男女比例分析-流年master出品)"))
    plot.grid()
    plot.show()

if __name__ == "__main__":
    chatProportion()
