List 绘制元组或列表的问题

我有一个数据集（它是真实数据集的一个示例），我正试图绘制它，它与第二列配合得很好，但是对于第一列（数据），它没有绘制，整个集合也没有正确绘制，它只显示第二列的结果。但是，它会正确地打印集合，并分别打印两列

import matplotlib.pyplot as plt
import pandas as pd
import numpy as np
import scipy
colunas = ["data", "valor"]
linhas = [([2,3,5,6,9,10,11,13,14,16,18,20,23,24,25],1),
([1,4,5,6,7,9,11,12,13,15,16,19,20,23,24],1),
([1,4,6,7,8,9,10,11,12,14,16,17,20,23,24],1),
([1,2,4,5,8,10,12,13,16,17,18,19,23,24,25],0),
([1,2,4,8,9,11,12,13,15,16,19,20,23,24,25],0),
([1,2,4,5,6,7,10,12,15,16,17,19,21,23,25],0),
([1,4,7,8,10,12,14,15,16,18,19,21,22,23,25],0),
([1,5,6,8,9,10,13,15,16,17,18,19,20,22,25],0),
([3,4,5,9,10,11,13,15,16,17,19,20,21,24,25],0),
([2,3,4,5,6,8,9,10,11,12,14,19,20,23,24],0),
([2,6,7,8,9,10,11,12,16,19,20,22,23,24,25],0),
([1,2,4,5,7,8,9,10,11,12,14,16,17,24,25],0),
([3,5,6,7,8,9,10,11,13,14,15,16,17,19,23],0)]
set = pd.DataFrame(columns=colunas, data=linhas)
#set = set.astype(int)
y = set['data']
x = set['valor']
y.plot(kind='box',subplots=True, layout=(4,4),sharex=True, sharey=True)
plt.show()

现在数据集在列表中，在元组中，在它们成为元组中的元组之前。 我得到的错误如下：

raise TypeError("no numeric data to plot")
TypeError: no numeric data to plot
