您可以使用Matplotlib库中的bar3d函数来绘制Python中的立体柱状图。在代码中,您需要导入numpy和matplotlib.pyplot库,并使用subplot和add_subplot函数创建一个3D子图。然后,您可以使用bar3d函数绘制立体柱状图。其中,x、y和z分别是每个柱子的坐标和高度。您可以使用dx和dy参数控制柱子的宽度和厚度。颜色可以通过color参数进行设置。最后,使用set_xticks、set_yticks和set_zlabel函数设置坐标轴刻度和标签,使用view_init函数调整视角,使用w_xaxis、w_yaxis和w_zaxis函数将背景设置为白色。请参考以下示例代码:
<<import numpy as np
import matplotlib.pyplot as plt
fig = plt.figure()
ax = fig.add_subplot(111, projection='3d')
x = np.arange(1,4 1,1)
y = np.arange(1,4 1,1)
hist = (np.random.randint(0, 1000, 16)).reshape((4,4))
zpos = 0
color = ('r','g','b','y')
dx = dy = 0.8
for i in range(4):
c = color[i]
ax.bar3d(range(4), [i * 4, [0 * 4, dx, dy, hist[i, :], color=c)
ax.set_xticks(x)
ax.set_xlabel('X')
ax.set_yticks(y)
ax.set_ylabel('Y')
ax.set_zlabel('Z')
ax.view_init(elev=30,azim=-60)
ax.w_xaxis.set_pane_color((1.0, 1.0, 1.0, 0.0))
ax.w_yaxis.set_pane_color((1.0, 1.0, 1.0, 0.0))
ax.w_zaxis.set_pane_color((1.0, 1.0, 1.0, 0.0))
plt.show()>><span class="em">1</span><span class="em">2</span><span class="em">3</span>
