Turn off error bars in Seaborn Bar Plot

Have you tried the ci argument? According to the documentation:

ci : float or None, optional Size of confidence intervals to draw around estimated values. If None, no bootstrapping will be performed, and error bars will not be drawn.

sns.barplot(x=df['Time'], y=df['Volume_Count'], ax=ax7, ci=None)

Complete example for @Diziet Asahi

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

df = sns.load_dataset('titanic')

# Usual case

# No error bars (ci=None)

Output for Usual case
