Three Staggered Values - Visualisation?
You could compare the relative values over time quite easily with a "stacked" graph, where each of the processes is a layer in the stack. In Pandas' plotting, it is referred to as an area plot.

Here is an example with some dummy data:

import pandas as pd
import numpy as np
import matplotlib.pyplot as plt

p1, p2, p3 = np.random.random(100), np.random.random(100), np.random.random(100)

df = pd.DataFrame([p1, p2, p3]).T
df.head(2)
# output
#              0         1         2
#    0  0.542490  0.099974  0.831589
#    1  0.988922  0.035026  0.752813

df.plot(kind="area", stacked=True); plt.show()




I think this might allow you to see the relative swings in each of the processes quite clearly - you could also shift the slightly to be in phase, which will make things easier.
