matplotlib畫直方圖和餅狀圖

文章最前: 我是Octopus,這個名字來源于我的中文名--章魚;我熱愛程式設計、熱愛算法、熱愛開源。所有源碼在我的個人github ;這部落格是記錄我學習的點點滴滴,如果您對 Python、Java、AI、算法有興趣,可以關注我的動态,一起學習,共同進步。

1)直方圖

# 需求:電影時長分布狀況
# 1、準備資料
time = [131,  98, 125, 131, 124, 139, 131, 117, 128, 108, 135, 138, 131, 102, 107, 114, 119, 128, 121, 142, 127, 130, 124, 101, 110, 116, 117, 110, 128, 128, 115,  99, 136, 126, 134,  95, 138, 117, 111,78, 132, 124, 113, 150, 110, 117,  86,  95, 144, 105, 126, 130,126, 130, 126, 116, 123, 106, 112, 138, 123,  86, 101,  99, 136,123, 117, 119, 105, 137, 123, 128, 125, 104, 109, 134, 125, 127,105, 120, 107, 129, 116, 108, 132, 103, 136, 118, 102, 120, 114,105, 115, 132, 145, 119, 121, 112, 139, 125, 138, 109, 132, 134,156, 106, 117, 127, 144, 139, 139, 119, 140,  83, 110, 102,123,107, 143, 115, 136, 118, 139, 123, 112, 118, 125, 109, 119, 133,112, 114, 122, 109, 106, 123, 116, 131, 127, 115, 118, 112, 135,115, 146, 137, 116, 103, 144,  83, 123, 111, 110, 111, 100, 154,136, 100, 118, 119, 133, 134, 106, 129, 126, 110, 111, 109, 141,120, 117, 106, 149, 122, 122, 110, 118, 127, 121, 114, 125, 126,114, 140, 103, 130, 141, 117, 106, 114, 121, 114, 133, 137,  92,121, 112, 146,  97, 137, 105,  98, 117, 112,  81,  97, 139, 113,134, 106, 144, 110, 137, 137, 111, 104, 117, 100, 111, 101, 110,105, 129, 137, 112, 120, 113, 133, 112,  83,  94, 146, 133, 101,131, 116, 111,  84, 137, 115, 122, 106, 144, 109, 123, 116, 111,111, 133, 150]

# 2、建立畫布
plt.figure(figsize=(20, 8), dpi=80)

# 3、繪制直方圖
distance = 2
group_num = int((max(time) - min(time)) / distance)

plt.hist(time, bins=group_num, density=True)

# 修改x軸刻度
plt.xticks(range(min(time), max(time) + 2, distance))

# 添加網格
plt.grid(linestyle="--", alpha=0.5)

# 4、顯示圖像
plt.show()

2)餅圖繪制

# 1、準備資料
movie_name = ['雷神3:諸神黃昏','正義聯盟','東方快車謀殺案','尋夢環遊記','全球風暴','降魔傳','追捕','七十七天','密戰','狂獸','其它']

place_count = [60605,54546,45819,28243,13270,9945,7679,6799,6101,4621,20105]

# 2、建立畫布
plt.figure(figsize=(20, 8), dpi=80)
#  notebook 裡,要設定下面兩行才能顯示中文
plt.rcParams['font.family'] = ['SimHei']
# PyCharm隻要下面一行,
#plt.rcParams['font.sans-serif'] = ['SimHei']
# 3、繪制餅圖
plt.pie(place_count, labels=movie_name, colors=['b','r','g','y','c','m','y','k','c','g','y'], autopct="%1.2f%%")

# 顯示圖例
plt.legend()

plt.axis('equal')

# 4、顯示圖像
plt.show()
