Trouble With Stacked Bar Graph Without Pooling

I have a clear idea of what I would like to plot, but I am not sure where to start using matplotlib/seaborn. I have ~999 unequal lines of 0s, 1s, and 2. Here is an example of one l

Solution 1:

With 1000 rows I guess you're better off if you display your data as an image using imshow rather than a bar chart. Put your data (0, 1 or 2) in an array of 999 rows and as many columns as the longest sequence, initilize that array with -1.

Example with just 100 rows for better readability:

import matplotlib.pyplot as plt
import numpy as np

# generate some sample data
n, m = 10, 20
a = np.random.randint(0, 3, (n,m))
s = np.random.randint(int(m/2), m, n)
for i in range(n):
    a[i,s[i]:] = -1

# show them as image
cmap = plt.matplotlib.colors.ListedColormap(['w', 'r', 'lime', 'b'])
plt.imshow(a, cmap=cmap)

You can then adjust axis ticks and labels as needed.
