I'm trying to normalize the y-axis of this plot, when I say normalize and leave on the same scale

import matplotlib.pyplot as plt
from matplotlib.gridspec import GridSpec
import numpy as np
from matplotlib.legend_handler import HandlerLine2D

Problem with python executable generated by pyinstaller Run-time error: 9 - subscript out of range 2

After rearranging the code a little more intuitively (creating the figure, setting it up next), and removing the assignments that were in the way (eg ax1 = plt.grid(axis='y', linestyle='-') ), what was missing was sharex=ax1, sharey=ax1 parameters in line that defines ax2 .

f = plt.figure()

ax1 = plt.subplot(1,2,1)

line4,=plt.plot(week, TNRF10FoldsAt, label='CV 10Folds com atributos Turma 4 - RF ')
line4,=plt.plot(week, TNRF10FoldsNoAt, label='CV 10Folds sem atributos Turma 4 - RF ')

plt.legend(handler_map={line4:HandlerLine2D(numpoints=4)})
plt.grid(axis='y', linestyle='-')
plt.xticks(week, my_xticks)
plt.yticks(np.arange(0, 1, 0.25))
plt.title('VN Random Forest com e sem atributos derivados. ')

ax2 = plt.subplot(1,2,2, sharex=ax1, sharey=ax1)

line1,  = plt.plot(week, TPRF10FoldsAt, label='CV 10Folds com atributos Turma 4 - RF ')
line2,  = plt.plot(week, TPRF10FoldsNoAt, label='CV 10Folds sem atributos Turma 4 - RF ')

plt.legend(handler_map={line1: HandlerLine2D(numpoints=4)})
plt.grid(axis='y', linestyle='-')
plt.xticks(week, my_xticks)

plt.show()
