soccerplots雷达图数字显示不全问题求助

使用soccerplots库绘制雷达图时，图中的数字被截断一半。已尝试调整z-order、绘图顺序、颜色、字体及透明度，但问题仍未解决。mplsoccer库可正常运行，推测需更新soccerplots包以解决z-order层级问题。

问题现象：雷达图的数值标签仅显示上半部分，下半部分被图层遮挡截断。

原代码：

import numpy as np
import matplotlib.pyplot as plt
from math import pi
from soccerplots.radar_chart import Radar

# Parameter names
params = ['xAssist', 'Key Passes', 'Crosses Into Box', 'Cross Completion %', 'Deep Completions',
          'Progressive Passes', 'Prog. Pass Accuracy', 'Dribbles', 'Progressive Runs',
          'PADJ Interceptions', 'Succ. Def. Actions', 'Def Duel Win %']

# Range values
ranges = [(0.0, 0.15), (0.0, 0.67), (0.06, 6.3), (19.51, 50.0), (0.35, 1.61),
          (6.45, 11.94), (62.9, 79.4), (0.43, 4.08), (0.6, 2.33),
          (4.74, 7.2), (8.59, 12.48), (50.66, 66.67)]

# Parameter values
values = [0.11, 0.53, 0.70, 27.66, 1.05, 6.84, 84.62, 4.56, 2.22, 5.93, 8.88, 64.29]


# Plot radar
fig, ax = radar.plot_radar(ranges=ranges, params=params, values=values, 
                           radar_color=['#B6282F', '#808080'], zorder=1, alphas=[0.3])

## instantiate object 
radar = Radar(background_color="#121212", patch_color="#28252C", label_color="#F0FFF0",
              range_color="#F0FFF0", fontfamily="Arial", )


plt.show()

1. 修正代码执行顺序 #

原代码存在核心逻辑错误：在调用radar.plot_radar()之后才实例化Radar对象，这会导致未定义行为，是引发显示问题的直接诱因。必须先创建Radar实例，再调用绘图方法。

2. 更新soccerplots包 #

soccerplots早期版本确实存在z-order层级问题，导致数值标签被雷达图层遮挡。执行以下命令更新到最新版本：

pip install --upgrade soccerplots

3. 修正后的完整代码 #

import numpy as np
import matplotlib.pyplot as plt
from soccerplots.radar_chart import Radar

# Parameter names
params = ['xAssist', 'Key Passes', 'Crosses Into Box', 'Cross Completion %', 'Deep Completions',
          'Progressive Passes', 'Prog. Pass Accuracy', 'Dribbles', 'Progressive Runs',
          'PADJ Interceptions', 'Succ. Def. Actions', 'Def Duel Win %']

# Range values
ranges = [(0.0, 0.15), (0.0, 0.67), (0.06, 6.3), (19.51, 50.0), (0.35, 1.61),
          (6.45, 11.94), (62.9, 79.4), (0.43, 4.08), (0.6, 2.33),
          (4.74, 7.2), (8.59, 12.48), (50.66, 66.67)]

# Parameter values
values = [0.11, 0.53, 0.70, 27.66, 1.05, 6.84, 84.62, 4.56, 2.22, 5.93, 8.88, 64.29]

# 先实例化Radar对象
radar = Radar(background_color="#121212", patch_color="#28252C", label_color="#F0FFF0",
              range_color="#F0FFF0", fontfamily="Arial")

# 再调用绘图方法
fig, ax = radar.plot_radar(ranges=ranges, params=params, values=values, 
                           radar_color=['#B6282F', '#808080'], zorder=1, alphas=[0.3])

plt.show()

4. 额外优化建议 #

如果更新包和修正顺序后仍有轻微截断，可尝试：

• 在Radar实例化时添加fontsize参数调整字体大小，例如fontsize=10
• 绘图后执行plt.tight_layout()自动调整图表布局，或通过ax.set_ylim()手动扩展y轴范围
