Align stacked bar charts usind pandas

问题

I'm trying to align all of the stacked bar charts having the same index. What's the best way of doing this?

This is my code so far:

xantho99 = [545/60, 6/60, 1688/60, 44/60]
buch99 = [51/60, 2/60, 576/60, 7/60]
myco99 = [519/60, 9/60, 889/60, 28/60]
cory99 = [247/60, 5/60, 1160/60, 28/60]
xantho90 = [545/60, 8/60, 989/60, 27/60]
buch90 = [51/60, 3/60, 523/60, 5/60]
myco90 = [519/60, 11/60, 802/60, 32/60]
cory90 = [247/60, 7/60, 899/60, 27/60]
xanthouc = [545/60, 0/60, 5407/60, 193/60]
buchuc = [51/60, 0/60, 1014/60, 20/60]
mycouc = [519/60, 0/60, 4644/60, 101/60]
coryuc = [247/60, 0/60, 2384/60, 77/60]
df = pd.DataFrame([xantho, xantho99, xantho90, buch, buch99, buch90, myco, myco99, myco90, cory, cory99, cory90], columns=['Prodigal', 'Cd-hit', 'PSOT', 'Zusammenführen'], index=["X", "X","X", "B", "B","B", "M", "M","M", "C", "C","C"])
df.columns.name = "Abschnitt"
current_palette = "blue", "green", "red", "yellow"
ax = df.plot.bar(stacked=True, title="Zeitbedarf der einzelnen Abschnitte (Xanthomonas)", xlim=(0, sum(xantho)*1.1), color=current_palette, rot=0)
ax.set_xlabel("Zeit in Stunden")

Thank You!

Here's the relevant code (should work if you put it at the bottom of the script in the question):

import pandas as pd
import numpy as np
import matplotlib.pyplot as plt
...
...
...
# Comment out old plot
# ax = df.plot.bar(stacked=True, title="Zeitbedarf der einzelnen Abschnitte (Xanthomonas)", xlim=(0, sum(xantho)*1.1), color=current_palette, rot=0)                                                         
# ax.set_xlabel("Zeit in Stunden")                                                                                                                   
spacing = [0, 0, 0, 1.0, 1.0, 1.0, 2.0, 2.0, 2.0, 3.0, 3.0, 3.0]
p1 = plt.bar(np.arange(12) + spacing, df['Prodigal'], color="blue", width=1.0, edgecolor="black")
p2 = plt.bar(np.arange(12) + spacing, df['PSOT'], bottom=df['Prodigal'], color="red", width=1.0, edgecolor="black")
p3 = plt.bar(np.arange(12) + spacing, df['Zusammenführen'], bottom=df['Prodigal'] + df['PSOT'], color="yellow", width=1.0, edgecolor="black")
p4 = plt.bar(np.arange(12) + spacing, df['Cd-hit'], bottom=df['Prodigal'] + df['PSOT'] + df['Zusammenführen'], color="green", width=1.0, edgecolor="black")
plt.legend((p1[0], p2[0], p3[0], p4[0]), ('Prodigal', 'PSOT', 'Zusammenführen', 'Cd-hit'))
plt.show()

Here's what pops up after you run this snippet:

I think this is what's desired, based on our discussion in comments. HTH, let me know if this is what you were looking for!
