I don't think there is a sage command for that, but you can use matplotlib(present by default in sage) to make these kind of plots. I have pasted a sample code from this site. If you run the code below you will see 3D bar plot.

```
from mpl_toolkits.mplot3d import Axes3D
import matplotlib.pyplot as plt
import numpy as np
fig = plt.figure()
ax1 = fig.add_subplot(111, projection='3d')
xpos = [1,2,3,4,5,6,7,8,9,10]
ypos = [2,3,4,5,1,6,2,1,7,2]
num_elements = len(xpos)
zpos = [0,0,0,0,0,0,0,0,0,0]
dx = np.ones(10)
dy = np.ones(10)
dz = [1,2,3,4,5,6,7,8,9,10]
ax1.bar3d(xpos, ypos, zpos, dx, dy, dz, color='#00ceaa')
plt.savefig('test.png')
```
