This sub-skill covers one capability of the Excel workflow. For reading/counting/Parquet optimization, see the parent workflow SKILL.md.
Step1 数据清洗与标准化。提取目标分析列,处理合并单元格(ffill),并利用正则表达式或类型转换清理数值字段,确保分析数据集的准确性。
import re
# 假设 target_col_x 和 target_col_y 是分析目标
# 处理合并单元格导致的缺失值
df['group_col'] = df['group_col'].fillna(method='ffill')
def clean_numeric_string(value):
if pd.isna(value): return None
# 保留数字、小数点和负号,移除空格及非法字符
cleaned = re.sub(r'[^\d\.\-]', '', str(value))
try:
return float(cleaned)
except ValueError:
return None
df['x_val'] = df['target_col_x'].apply(clean_numeric_string)
df['y_val'] = df['target_col_y'].apply(clean_numeric_string)
# 过滤无效数据
df_clean = df.dropna(subset=['x_val', 'y_val']).copy()
Step2 执行多维度统计分析。计算分类占比、均值、标准差,并构建交叉分析表(crosstab/pivot),为可视化提供数据支撑。
# 分类统计与占比
stats_summary = df_clean.groupby('group_col')['y_val'].agg(['count', 'mean', 'std', 'min', 'max'])
stats_summary['percentage'] = (stats_summary['count'] / stats_summary['count'].sum()) * 100
# 添加总计行
total_row = pd.DataFrame(df_clean[['y_val']].agg(['count', 'mean']).T)
total_row.index = ['Total']
# 交叉分析示例
pivot_table = pd.pivot_table(df_clean, values='y_val', index='group_col', columns='category_col', aggfunc='count', fill_value=0)
Step3 生成高分辨率可视化图表。包含散点图、线性趋势线(R²、p值)、箱线图或柱状图组合,并配置中文字体与美化参数。
import matplotlib.pyplot as plt
import matplotlib
from scipy import stats
import numpy as np
# 字体配置:优先使用 SimHei 或 DejaVu Sans 确保中文显示
matplotlib.rcParams['font.sans-serif'] = ['SimHei', 'WenQuanYi Zen Hei', 'DejaVu Sans']
matplotlib.rcParams['axes.unicode_minus'] = False
x = df_clean['x_val'].values
y = df_clean['y_val'].values
# 线性回归计算
slope, intercept, r_value, p_value, std_err = stats.linregress(x, y)
line = slope * x + intercept
plt.figure(figsize=(12, 8), dpi=300)
