我试图生成一个有四个季度的图，每个季度都有一些关于该季度的文字。然而，当我试图 Package 文字时，我不知道如何设置文字的限制。例如，在附图中，我想将文字限制为x=0。然而，它将一直持续到x轴极限的结束。请找到随附的代码和代码生成的相应图。

import matplotlib
%matplotlib inline
import matplotlib.pyplot as plt

import numpy as np
from textwrap import wrap

font = {'size': 22}
matplotlib.rc('font', **font)
fig = plt.figure(figsize=(8, 8))
plt.axis([-10, 10, -10, 10])

ax = plt.gca()

ax.spines['left'].set_position('center')
ax.spines['bottom'].set_position('center')

ax.spines['right'].set_visible(False)
ax.spines['top'].set_visible(False)

plt.xlabel('Energy ($kWh$)')
ax.xaxis.set_label_coords(0.85, .48)
ax.xaxis.set_ticks_position('bottom')
ax.set_xlim(-10, 10)
ax.xaxis.set_ticks([])

plt.ylabel('Discomfort ($\%$)', rotation=0)
ax.yaxis.set_label_coords(0.7, 0.01)
ax.yaxis.set_ticks_position('left')
ax.set_ylim(-10, 10)
ax.yaxis.set_ticks([])

ax.annotate(
    'Reference Point', xy=(0, 0), xycoords='data',
    xytext=(-10, 2), textcoords='data', wrap=True,
    arrowprops=dict(facecolor='black'))

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!"

ax.text(-10, 3.5, t, ha='left', wrap=True, fontsize=20)
plt.tight_layout()
plt.savefig('sample.png')
