seaborn\\matplotlib\\pandas 绘图未显示 ylabel

Question

I'm trying to create a violin plot for some data, but for some reason my ylabel won't change.

fig, ax = plt.subplots(figsize=(10, 5))
ax.set_title('Violin plots for fat content per lab', size=18, weight='bold')
ax.set_ylabel('Fat content (%)')

sns.violinplot(data=df_eggs, x='Lab', y='Fat_Content', ax=ax);

I'm using Jupyter Notebook and I imported pandas, seaborn and matplotlib beforehand. Here is the result .

Answer 1

The commentor is right. Just change the order of things like this:

fig, ax = plt.subplots(figsize=(10, 5))
ax.set_title('Violin plots for fat content per lab', size=18, weight='bold')
sns.violinplot(data=df_eggs, x='Lab', y='Fat_Content', ax=ax)
ax.set_ylabel('Fat content (%)')

When you put the ax.set_ylabel before the sns.violinplot , the label you set with the ax.set_ylabel is being overwritten with the y label written by the sns.violinplot .
