bar plot in 3d following a given line

Question

I want to draw a bar plot in 3d. I know how to do that using the following code:

from mpl_toolkits.mplot3d import Axes3D
import matplotlib.pyplot as plt
import numpy as np
fig = plt.figure(figsize=(10,10))
ax = fig.add_subplot(111, projection='3d')
nbins = 50
# for c, z in zip(['r', 'g', 'b', 'y'], [30, 20, 10, 0]):
ys = np.random.normal(loc=10, scale=10, size=2000)

hist, bins = np.histogram(ys, bins=nbins)
xs = (bins[:-1] + bins[1:])/2

ax.bar(xs, hist, zs=30, zdir='y', color='r', ec='r', alpha=0.8)

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

plt.show()

This will render something like this: https://i.stack.imgur.com/KK2If.png

However, my goal is to make the bar plot follows a line that I give as parameter. For example here, the parameter zdir='y' makes the plot have its current direction. Ideally I want to pass a parameter that makes the plot follows a given line for example y=2x+1.

Could someone help arrive at the desired result?
