Question

我使用以下列从uniprot文件构建了一个数据框：

(index(protein_id),length, organism, sequence,acidic, polar,hydrophobic,color,width)

参数acidic，hydrophobic和polar是百分比（即1到100之间的数字），width介于0-1和color之间是4个数字的集合，例如：(0.5, 0.0, 0.0, 1.0)

我尝试以下列方式构建3d plot：

from mpl_toolkits.mplot3d import Axes3D
import matplotlib.pyplot as plt
import numpy as np

fig = plt.figure()
ax = fig.add_subplot(111, projection='3d')


charge_sum = 0
display(df)
for index, record in prot_df.iterrows():
    xs=int(record['acidic'])
    ys=int(record['polar'])
    zs=int(record['hydrophobic'])
    cs=record['color']
    width=record['width']
    ax.bar(xs, ys, zs, zdir='y', color=cs, alpha=width)

ax.set_xlabel('X')
ax.set_ylabel('Y')
ax.set_zlabel('Z')

plt.show()

但是我收到以下错误：

>TypeError                                 Traceback (most recent call last)

有人可以帮助我摆脱这个错误吗？

3D列使用dataFrame和matplotlib绘制
