python - 绘制包含字典列表的字典中的值

Question

我正在尝试绘制图来看看我所做的是否正确，但不太确定如何做到这一点。

我有这个字典:

k = {'Boston': [{'name': 'Jayson Tatum','rebounds': 8.0, 'assists': 4.4, 'points': 26.9}, {'name': 'Jaylen Brown','rebounds': 6.1, 'assists': 3.5, 'points': 23.6}, {'name': 'Marcus Smart', 'rebounds': 3.8, 'assists': 5.9, 'points': 12.1}], 'Phoenix': [{'name': 'Devin Booker', 'rebounds': 5.0, 'assists': 4.8, 'points': 26.8}, {'name': 'Deandre Ayton', 'rebounds': 10.2, 'assists': 1.4, 'points': 17.2}, {'name': 'Chris Paul', 'rebounds': 4.4, 'assists': 0.0, 'points': 14.7}], 'Philadelphia': [{'name': 'Tyrese Maxey', 'rebounds': 3.2, 'assists': 4.3, 'points': 17.5}, {'name': 'Tobias Harris', 'rebounds': 6.8, 'assists': 3.5, 'points': 17.2}, {'name': 'Georges Niang','rebounds': 2.7, 'assists': 1.3, 'points': 9.2}], 'Milwaukee': [{'name': 'Giannis Antetokounmpo', 'rebounds': 11.6, 'assists': 5.8, 'points': 29.9}, {'name': 'Khris Middleton','rebounds': 5.4, 'assists': 5.4, 'points': 20.1}, {'name': 'Jrue Holiday','rebounds': 4.5, 'assists': 6.8, 'points': 18.3}], 'Golden State': [{'name': 'Stephen Curry', 'rebounds': 5.2, 'assists': 6.3, 'points': 25.5}, {'name': 'Klay Thompson', 'rebounds': 3.9, 'assists': 2.8, 'points': 20.4}, {'name': 'Jordan Poole', 'rebounds': 3.4, 'assists': 4.0, 'points': 18.5}], 'Miami': [{'name': 'Jimmy Butler', 'rebounds': 5.9, 'assists': 5.5, 'points': 21.4}, {'name': 'Tyler Herro', 'rebounds': 5.0, 'assists': 4.0, 'points': 20.7}, {'name': 'Bam Adebayo', 'rebounds': 10.1, 'assists': 3.4, 'points': 19.1}], 'Dallas': [{'name': 'Luka Dončić''rebounds': 9.1, 'assists': 8.7, 'points': 28.4}, {'name': 'Jalen Brunson', rebounds': 3.9, 'assists': 4.8, 'points': 16.3}, {'name': 'Tim Hardaway Jr.', 'rebounds': 3.7, 'assists': 2.2, 'points': 14.2}], 'Memphis': [{'name': 'Ja Morant', 'rebounds': 5.7, 'assists': 6.7, 'points': 27.4}, {'name': 'Dillon Brooks','rebounds': 3.2, 'assists': 2.8, 'points': 18.4}, {'name': 'Desmond Bane', 'rebounds': 4.4, 'assists': 2.7, 'points': 18.2}]}

这个字典有一个团队作为键，一个列表作为值，这个列表包含三个字典，每个玩家一个。

我想知道如何绘制这个，我想在打印反弹、助攻或点之间进行选择，我如何指定要绘制哪一个？

我尝试将 k 转换为数据框，但行仍然是字典列表，我不知道如何访问它来进行绘图。

我也尝试过这样的事情:

for team in k:
    players = top_players_in_teams[team]
    names = list(players.keys())

    values = [value[wantedType] for value in list(players.values())]

    team_bars = ax.bar(names, values, label=team, zorder=3)
    team_bars.set_label(team)

ax.set_title("SOMETHING")
ax.legend(title="TeaM", bbox_to_anchor=(1.05, 1))

plt.grid(b=True, which="major", axis="y", zorder=0)
plt.xticks(rotation=90)

Answer 1

您可以首先将数据转换为更结构化的数据框，然后根据需要进行绘图。

import pandas as pd
import matplotlib.pyplot as plt

mydict = {}

i = 0
for team in k:
    for player in k[team]:
        mydict[i] = [team, player["name"], player["rebounds"], player["assists"], player["points"]]
        i += 1

df = pd.DataFrame.from_dict(mydict, orient="index", columns=["team", "name", "rebounds", "assists", "points"])

print(df)

产生:

            team                   name  rebounds  assists  points
0         Boston           Jayson Tatum       8.0      4.4    26.9

作为示例图:

df.plot(x='name', y='rebounds', kind='bar')
plt.show()
