代码说明

数据模拟

模拟了两支球队(TEAM_A, TEAM_B)各100次进攻
包含时间、动作、区域、速度等12个维度的数据

核心功能

基础统计：总反击次数、进球数、射门数
效率计算：进球效率、射门效率、成功率
时间分析：不同时间段的反击效果
可视化：4个图表对比两队表现

效率判断标准

反击成功率 = (进球数 + 射门数 * 0.5) / 总反击次数 * 100

运行结果示例

============================================================
📊 基础统计：
TEAM_A:
  总反击次数: 95
  反击进球数: 12
  反击射门数: 28
  反击得分率: 12.63%
TEAM_B:
  总反击次数: 88
  反击进球数: 15
  反击射门数: 25
  反击得分率: 17.05%
