[FIXED] Labeling horizontal bar using matplotlib bar_label

Issue

I'd like to display the value of the bar on each bar with pyplot.barh() and ax.bar_label.

I've read the document https://matplotlib.org/stable/gallery/lines_bars_and_markers/bar_label_demo.html but it didn't help. Please help.

# Prepare & sort the data
df = pd.DataFrame({"coins": ["BTC", "ETH", "BNB", "XRP", "SOL", "ADA"],
                   "dominance": [42.08, 19.38, 3.68, 1.73, 1.55, 1.51]})
df = df.sort_values(by=["dominance"])

# Plot horizontal bar graph
plt.figure(figsize=[10, 9])
plt.barh(df.coins, df.dominance)

Solution

the issue is that the bar_label is a new feature and available in matplotlib version 3.4 or later - ref this link. Check the version of matplotlib using

import matplotlib 
print('matplotlib: {}'.format(matplotlib.__version__))

Upgrade to v3.4 or latest version using pip install matplotlib --upgrade. You will need to include the code in the link you provided and as mentioned by JohanC and be able to see bar labels
