如何返回使用xlwings在Python在Excel中matplotlib图表？

Question

我是新来的Python和Xlwings。我想创建一个UDF在Excel中返回一个“箱线图”。表在Excel中有两列“Sales_Region”和“总销售额”。

在运行下面的代码，我收到错误“所需的对象”。我认为错误主要是由于装修的不正确使用。寻求帮助！

import seaborn as sns, numpy as np
import matplotlib.pyplot as plt
import xlwings as xw
import pandas as pd
from pandas import DataFrame



@xw.func
@xw.arg('df', pd.DataFrame, index = False, header=True)
@xw.arg('x_name', category = str)
@xw.arg('y_name', category = str)

def BOX_Plot(df,x_name,y_name):

    dt = pd.DataFrame(df)
    names = x_name
    bill =  y_name


    sns.set_style("whitegrid")
    ax = sns.boxplot(x=names, y=bill, data=dt)

    medians = dt.groupby([names])[bill].median().values
    median_labels = [str(np.round(s, 2)) for s in medians]

    pos = range(len(medians))
    for tick,label in zip(pos,ax.get_xticklabels()):
        ax.text(pos[tick], medians[tick], median_labels[tick], 
                horizontalalignment='center', size='x-small', color='w', weight='semibold')

    plt.show()

    return "Done!"

代码是完美的，我忘了在VBA工具添加Xlwings参考。
