python - No whitespace between Seaborn barplot bars

Question

I created a Seaborn barplot using the code below (it comes from https://www.machinelearningplus.com/plots/top-50-matplotlib-visualizations-the-master-plots-python/)

I would like all the bars to stack up without whitespace, but have been unable to do so. If I add width it complains about multiple values for width in barh. This is probably as seaborn has its own algo to determine the width. Is there anyway around it?

import pandas as pd
import matplotlib.pyplot as plt
import seaborn as sns

# Read data
df = pd.read_csv("https://raw.githubusercontent.com/selva86/datasets/master/email_campaign_funnel.csv")

# Draw Plot
plt.figure(figsize=(13, 10), dpi=80)
group_col = 'Gender'
order_of_bars = df.Stage.unique()[::-1]
colors = [plt.cm.Spectral(i/float(len(df[group_col].unique())-1)) for i in
          range(len(df[group_col].unique()))]

for c, group in zip(colors, df[group_col].unique()):
    sns.barplot(x='Users', y='Stage', data=df.loc[df[group_col]==group, :],
                order=order_of_bars, color=c, label=group)

# Decorations    
plt.xlabel("$Users$")
plt.ylabel("Stage of Purchase")
plt.yticks(fontsize=12)
plt.title("Population Pyramid of the Marketing Funnel", fontsize=22)
plt.legend()
plt.show()

无论如何都不是 matplotlib 专家，所以可能有更好的方法来做到这一点。也许您可以执行以下操作，类似于此答案中的方法：

# Draw Plot
fig, ax = plt.subplots(figsize=(13, 10), dpi=80)
...

for c, group in zip(colors, df[group_col].unique()):
    sns.barplot(x='Users', y='Stage', data=df.loc[df[group_col]==group, :],
                order=order_of_bars, color=c, label=group, ax=ax)

# Adjust height    
for patch in ax.patches:
    current_height = patch.get_height()
    patch.set_height(1)
    patch.set_y(patch.get_y() + current_height - 1)
