python bar chart total label on bar-CodePudding

plt.figure(figsize = (8,5))
sns.countplot(data = HRdfMerged, x = 'Gender', hue='Attrition').set_title('Gender vs Attrition')

I'm having a hard time adding a label to the top of my bar that states the total number. I have tried many different ways but can't get it right. Im using matplotlib. Picture of bar chart added.

Once you have called sns.countplot, we will explore the list ax.patches to get information from the bars and place the texts you want:


# Imports.
import matplotlib.pyplot as plt
import seaborn as sns

# Load a dataset and replicate what you have in the question, since you did
# not provide any data to help us help you. 
data = sns.load_dataset("titanic")
fig, ax = plt.subplots() # Use the object-oriented approach with Matplotlib when you can.
sns.countplot(data=data, x="class", hue="who", ax=ax)
ax.set_title("title goes here")
fig.show()

# For each bar, grab its coordinates and colors, find a suitable location
# for a text and place it there.
for patch in ax.patches:
    x0, y0 = patch.get_xy()   # Bottom-left corner. 
    x0  = patch.get_width()/2 # Middle of the width.
    y0  = patch.get_height()  # Top of the bar
    color = patch.get_facecolor()
    ax.text(x0, y0, str(y0), ha="center", va="bottom", color="white", clip_on=True, bbox=dict(ec="black",
                                                                                              fc=color))

Play around with the kwargs of ax.text to get the result you prefer. An alternative:

ax.text(x0, y0, str(y0), ha="center", va="bottom", color=color, clip_on=True)
