我来为您创建一个足球门前抢点射门次数对比的统计案例,这个案例将模拟分析两位前锋的抢点射门数据。

数据准备和可视化分析

import pandas as pd
import numpy as np
import matplotlib.pyplot as plt
import seaborn as sns
from datetime import datetime, timedelta
# 设置中文显示
plt.rcParams['font.sans-serif'] = ['SimHei']  # 用来正常显示中文标签
plt.rcParams['axes.unicode_minus'] = False    # 用来正常显示负号
# 生成模拟数据
np.random.seed(42)
# 创建两名球员的数据
players = ['梅西', 'C罗']
matches = [f'第{i}轮' for i in range(1, 21)]  # 20轮联赛
data = []
for player in players:
    for match in matches:
        # 生成抢点射门数据（包含射正、射偏、被封堵等）
        total_shots = np.random.randint(3, 15)  # 总抢点射门次数
        shots_on_target = int(total_shots * np.random.uniform(0.4, 0.7))  # 射正
        shots_off_target = int((total_shots - shots_on_target) * np.random.uniform(0.3, 0.6))  # 射偏
        shots_blocked = total_shots - shots_on_target - shots_off_target  # 被封堵
        goals = int(shots_on_target * np.random.uniform(0.2, 0.6))  # 进球数
        data.append({
            '球员': player,
            '比赛': match,
            '总射门': total_shots,
            '射正': shots_on_target,
            '射偏': shots_off_target,
            '被封堵': shots_blocked,
            '进球数': goals
        })
df = pd.DataFrame(data)
print("=== 模拟数据预览 ===")
print(df.head(10))
print(f"\n数据维度: {df.shape}")
print(f"数据描述: \n{df.describe()}")

总射门次数对比

# 总射门次数统计
total_shots_by_player = df.groupby('球员')['总射门'].agg(['sum', 'mean', 'std']).round(2)
print("=== 抢点射门总次数对比 ===")
print(total_shots_by_player)
# 折线图展示每轮射门次数变化
fig, ax = plt.subplots(figsize=(12, 6))
for player in players:
    player_data = df[df['球员'] == player]
    ax.plot(player_data['比赛'], player_data['总射门'], 
            marker='o', label=player, linewidth=2)
ax.set_xlabel('比赛轮次', fontsize=12)
ax.set_ylabel('抢点射门次数', fontsize=12)
ax.set_title('每轮比赛抢点射门次数对比', fontsize=14, fontweight='bold')
ax.legend()
ax.grid(True, alpha=0.3)
# 添加平均线
for player in players:
    avg = df[df['球员'] == player]['总射门'].mean()
    ax.axhline(y=avg, linestyle='--', alpha=0.5, 
               label=f'{player}平均: {avg:.2f}')
ax.legend()
plt.xticks(rotation=45)
plt.tight_layout()
plt.show()

射门质量对比

# 射正率计算
df['射正率'] = df['射正'] / df['总射门'] * 100
df['进球率'] = df['进球数'] / df['总射门'] * 100
# 对比射门质量
quality_stats = df.groupby('球员').agg({
    '射正率': 'mean',
    '进球率': 'mean',
    '进球数': 'sum'
}).round(2)
print("=== 射门质量对比 ===")
print(quality_stats)
# 箱线图展示射正率分布
fig, axes = plt.subplots(1, 2, figsize=(14, 6))
# 射正率箱线图
sns.boxplot(data=df, x='球员', y='射正率', ax=axes[0])
axes[0].set_title('射正率分布对比', fontsize=12, fontweight='bold')
axes[0].set_ylabel('射正率 (%)')
# 进球率箱线图
sns.boxplot(data=df, x='球员', y='进球率', ax=axes[1])
axes[1].set_title('进球率分布对比', fontsize=12, fontweight='bold')
axes[1].set_ylabel('进球率 (%)')
plt.tight_layout()
plt.show()

累计射门和进球对比

# 计算累计数据
df_sorted = df.sort_values(['球员', '比赛']).reset_index(drop=True)
df_sorted['累计射门'] = df_sorted.groupby('球员')['总射门'].cumsum()
df_sorted['累计进球'] = df_sorted.groupby('球员')['进球数'].cumsum()
# 绘制累计对比图
fig, axes = plt.subplots(2, 1, figsize=(14, 10))
# 累计射门
for player in players:
    player_data = df_sorted[df_sorted['球员'] == player]
    axes[0].plot(player_data['比赛'], player_data['累计射门'], 
                marker='s', label=player, linewidth=2)
axes[0].set_title('累计抢点射门次数对比', fontsize=14, fontweight='bold')
axes[0].set_ylabel('累计射门次数')
axes[0].legend()
axes[0].grid(True, alpha=0.3)
# 累计进球
for player in players:
    player_data = df_sorted[df_sorted['球员'] == player]
    axes[1].plot(player_data['比赛'], player_data['累计进球'], 
                marker='^', label=player, linewidth=2)
axes[1].set_title('累计进球数对比', fontsize=14, fontweight='bold')
axes[1].set_xlabel('比赛轮次')
axes[1].set_ylabel('累计进球数')
axes[1].legend()
axes[1].grid(True, alpha=0.3)
plt.xticks(rotation=45)
plt.tight_layout()
plt.show()

射门位置分布热力图

# 模拟射门位置数据（假设使用场地的相对位置）

        # 梅西更多在禁区弧顶附近
        for _ in range(n_shots):
            x = np.random.uniform(0.3, 0.7)
            y = np.random.normal(0.15, 0.1)
            locations.append((x, max(0.05, min(0.25, y))))

    # 创建热力图
    heatmap, xedges, yedges = np.histogram2d(locations[:, 0], locations[:, 1], 
                                             bins=20, range=[[0, 1], [0, 0.4]])
    im = axes[i].imshow(heatmap.T, origin='lower', 
                        extent=[0, 1, 0, 0.4],
                        aspect='auto', cmap='OrRd')
    # 添加球场标记
    axes[i].axhline(y=0.25, color='blue', linestyle='--', alpha=0.5)  # 禁区线
    axes[i].axhline(y=0.35, color='blue', linestyle='--', alpha=0.5)  # 球门线
