Y axis label not being saved when trying to save a plot as a pdf-CodePudding

currently I am trying to save a matplotlib plot as a PDF, however the Y axis is not being shown in the final figure despite being displayed in the plot. More specifically, I have the following subplots:

import matplotlib.pyplot as plt
from numpy import random

    sizes=22
    
    x1 = random.randint(2000, size=(125))
    x2 = random.randint(1000, size=(125))
    plt.subplot(2, 3, 1)
    plt.plot(x1, color='red')
    plt.plot(x2, color='blue')
    plt.yticks(fontsize=sizes)
    plt.xticks(fontsize=sizes)
    plt.title("Plot 1", fontsize=sizes)
    plt.gcf().text(-0.02,0.45, "Y-axis", ha="center", va="center", rotation=90, fontsize=sizes)
    
    x1 = random.randint(2000, size=(125))
    x2 = random.randint(1000, size=(125))
    plt.subplot(2, 3, 2)
    plt.plot(x1, label="Sobriedade", color='red')
    plt.plot(x2, label="Ebriedade", color='blue')
    plt.yticks(fontsize=sizes)
    plt.xticks(fontsize=sizes)
    leg = pp.legend(loc='lower center',fontsize=sizes, bbox_to_anchor=[0.5, 1.25], ncol=2)
    plt.title("Plot 2", fontsize=sizes)
    
    
    x1 = random.randint(2000, size=(125))
    x2 = random.randint(1000, size=(125))
    plt.subplot(2, 3, 3)
    plt.plot(x1, color='red')
    plt.plot(x2, color='blue')
    plt.yticks(fontsize=sizes)
    plt.xticks(fontsize=sizes)
    plt.title("Plot 3", fontsize=sizes)
    
    
    x1 = random.randint(2000, size=(125))
    x2 = random.randint(1000, size=(125))
    plt.subplot(2, 3, 4)
    plt.plot(x1, color='red')
    plt.plot(x2, color='blue')
    plt.yticks(fontsize=sizes)
    plt.xticks(fontsize=sizes)
    plt.title("Plot 4", fontsize=sizes)
    
    
    x1 = random.randint(2000, size=(125))
    x2 = random.randint(1000, size=(125))
    plt.subplot(2, 3, 5)
    plt.plot(x1, color='red')
    plt.plot(x2, color='blue')
    plt.yticks(fontsize=sizes)
    plt.xticks(fontsize=sizes)
    plt.title("Plot 5", fontsize=sizes)
    plt.xlabel('X-Axis', fontsize=sizes)
    
    
    x1 = random.randint(2000, size=(125))
    x2 = random.randint(1000, size=(125))
    plt.subplot(2, 3, 6)
    plt.plot(x1, color='red')
    plt.plot(x2, color='blue')
    plt.yticks(fontsize=sizes)
    plt.xticks(fontsize=sizes)
    plt.title("Plot 6", fontsize=sizes)
    
    plt.rcParams['figure.figsize'] = (18, 14)
    plt.tight_layout()
    plt.show()

In this line specifically:

plt.gcf().text(-0.02,0.45, "Y-axis", ha="center", va="center", rotation=90, fontsize=sizes)

It is an attempt to add a describing label to the left side of the overall plot. It works when plotting. However when I do plt.savefig() The said side label is not there.

The above image is a result from the example above. Therefore, when i do plt.savefig() i was expecting the y-axis label to be also saved in the figure. However, it isn't saved. This is what happens actually:

I'd like to know how can I make sure that the label on y-axis is actually saved when i save the figure?
