如何在不均匀的绘图中显示xtick以正确显示？

Question

Uneven plot in the x-axis

我正在尝试使用matplotlib绘制x轴上不均匀的图。但是x-tick没有显示在正确的位置。这是我上传的图片的python代码。X标记显示在图像的左下角，而不是每个数据点的下方。

import numpy as np 
import matplotlib.pyplot as plt 

ticks = [0.0369, 11.58, 13.41, 13.78, 15.2609, 24.9, 26.7, 61.65]
xi = list(range(len(ticks)))

rmse_before_without_cm = ([0, 5.6290,  6.5244, 7.7890, 6.0990, 11.1103, 20.1758, 30.4631])
std_error_rmse_before_without_cm = np.array([0, 0, 0, 0,  0,  0, 0, 0])

rmse_before_with_cm = np.array([0, 4.4034, 4.4712, 3.7395,  3.7687, 7.2956, 2.8387, 19.4628])
std_error_rmse_before_with_cm = np.array([0, 0, 0, 0, 0, 0, 0, 0])

X_max = 62 
X_var = ticks
L = len(X_var) # number of x values

Y_var_1 = rmse_before_without_cm 
Y_var_err1 = std_error_rmse_before_without_cm 

Y_var_2 = rmse_before_with_cm 
Y_var_err2 = std_error_rmse_before_with_cm

plt.rcParams["figure.figsize"] = [6.4, 4.8]
plt.rcParams['axes.linewidth'] = 2


plt.errorbar(X_var,Y_var_1,Y_var_err1,linestyle='None',markersize = 8,\
             marker = '+', capsize = 2, color = 'magenta', label = 'RMSE Before without Joined Cloud Mask')

plt.errorbar(X_var,Y_var_2,Y_var_err2,linestyle='None',markersize = 8,\
             marker = '^', capsize = 2, color = 'black', label = 'RMSE Before with Joined Cloud Mask')

FS = 18 
FS2 = 16
plt.xlabel('Cloud Cover $\%$', size=FS)
plt.ylabel('RMSE', size=FS)
plt.title('RMSE vs Cloud Cover $\%$', size=FS)

plt.yticks(fontsize = FS - 2) 
plt.xticks(xi, ticks)
plt.legend(fontsize = FS2-2) 
plt.show()

Answer 1

将plt.xticks(xi, ticks)更改为plt.xticks(ticks)

您可能想格式化字体等，以获得一些可读的东西。
