Split string xticks into multiple lines (matplotlib)

I have a matplotlib boxplot with very long strings as xticks. Is there a way to automatically split them into multiple lines to make the plot more clean? I am using the seaborn function barplot to create the graph.

This is the plot:enter image description here

And the code i use to create it:

plt.figure(figsize=(15,13))
sns.barplot(x="Component",y="TTTR",color = "C0",data=new,dodge=False,edgecolor="black",zorder=3)
plt.xticks(rotation=90)
plt.grid(axis='y',zorder=0)
plt.title("10 most impactful components",size=30,y=1.04,**pfont)
plt.ylabel("Impact (Sum TTR in h)")
plt.xlabel('Component')
plt.tight_layout()

seaborn.barplot returns a matplotlib.Axes object so you could use Axes.set_xticklabels to update the labels afterwards, e.g. 

import textwrap

max_width = 20
ax = sns.barplot(...)
ax.set_xticklabels(textwrap.fill(x.get_text(), max_width) for x in ax.get_xticklabels())

Found a workaround: Replacing the label column in the pandas dataframe with the labels from this answer

new.Component = [re.sub("(.{20})", "\\1\n", label, 0, re.DOTALL) for label in new.Component]
sns.barplot(x="Component",y="TTTR",color ="C0",data=new,dodge=False,edgecolor="black",zorder=3)
