python-matplotlib如何设置网格大小

如图，我想将网格的长宽设置一样大，应该怎么设置？

代码如下：

import pandas as pd
from matplotlib import pyplot as plt
import matplotlib as mpl
import numpy as np
plt.style.use('ggplot')
plt.rcParams['font.sans-serif'] = ['SimHei']
data = pd.read_excel(r"C:\Users\MrC\Desktop\data.xlsx")
data_distance = np.genfromtxt(r"C:\Users\MrC\Desktop\data.csv", skip_header=1,
                         delimiter=',', usecols=(2,))
data_pitch = np.genfromtxt(r"C:\Users\MrC\Desktop\data.csv", skip_header=1,
                         delimiter=',', usecols=(4,))
data_pitch = np.deg2rad(data_pitch)
s = np.cos(data_pitch)
s = data_distance*s
plt.plot(s,
         data.height,
         linestyle='-',
         color='blue'，
         marker='o',  # 设置每个数据的标识，此处为空心圆
         markersize=6,  # 设置空心圆大小
         markeredgecolor='black',  # 设置标识的边缘颜色
         markerfacecolor='brown'
         )
plt.plot(s,
         data.test,
         linestyle='-',
         )
ax = plt.gca()
ax.tick_params(axis='both', labelsize=25,)

xlocator = mpl.ticker.MultipleLocator(5)
ylocator = mpl.ticker.MultipleLocator(5)
ax.xaxis.set_major_locator(xlocator)
ax.yaxis.set_major_locator(ylocator)
plt.show()

看起来你 X,Y坐标轴一致，可以尝试设置图片大小试试，

增加plt.rcParams['figure.figsize'] = (8.0, 8.0)

试试！！！
