+# 文本自动换行
+
+Matplotlib can wrap text automatically, but if it's too long, the text will be displayed slightly outside of the boundaries of the axis anyways.
+
+![文本自动换行示例](https://matplotlib.org/_images/sphx_glr_autowrap_001.png)
+
+```python
+import matplotlib.pyplot as plt
+
+fig = plt.figure()
+plt.axis([0, 10, 0, 10])
+t = ("This is a really long string that I'd rather have wrapped so that it "
+     "doesn't go outside of the figure, but if it's long enough it will go "
+     "off the top or bottom!")
+plt.text(4, 1, t, ha='left', rotation=15, wrap=True)
+plt.text(6, 5, t, ha='left', rotation=15, wrap=True)
+plt.text(5, 5, t, ha='right', rotation=-15, wrap=True)
+plt.text(5, 10, t, fontsize=18, style='oblique', ha='center',
+         va='top', wrap=True)
+plt.text(3, 4, t, family='serif', style='italic', ha='right', wrap=True)
+plt.text(-1, 0, t, ha='left', rotation=-15, wrap=True)
+
+plt.show()
+```
