# 1. 读取Excel数据
file_path = 'data.xlsx'
df = pd.read_excel(file_path)

# 2. 创建Excel工作簿并写入数据
wb = Workbook()
ws = wb.active

# 将DataFrame数据写入工作表
for r in dataframe_to_rows(df, index=False, header=True):
    ws.append(r)

# 3. 生成柱状图（Sales数据）
bar_chart = BarChart()
data = Reference(ws, min_col=2, min_row=2, max_row=len(df) + 1)  # Sales列数据
categories = Reference(ws, min_col=1, min_row=2, max_row=len(df) + 1)  #
