已知数据为随机4*4矩阵，给我一段完整的南丁格尔玫瑰图的代码

答：下面是一段南丁格尔玫瑰图的代码：import matplotlib.pyplot as pltdata = [[1,2,3,4], [4,1,2,3], [3,4,1,2], [2,3,4,1]]labels = ['A', 'B', 'C', 'D']plt.figure()plt.title("南丁格尔玫瑰图")plt.pie(data[0], labels=labels, autopct='%.2f%%')for i in range(1, 4):
plt.pie(data[i], labels=labels, radius=0.5*i, autopct='%.2f%%', startangle=90)plt.axis('equal')plt.legend()plt.show()
