Is it possible to get the json value of a matplotlib object?

Question

I'm working on code generation with deep learning. I have a code (the ground truth) using matplotlib to plot a figure. My trained neural network will generate too a code to plot the figure. I would like to compare automatically both plot (it is not clever to compare the code because two different codes could return the same result).

I could compare both images but it is not convenient, is it possible to compare two plot objects with a boolean response?

For example, i have the following ground truth:

import matplotlib.pyplot as plt
import numpy as np

x = np.linspace(0, 10, 100)

fig, ax = plt.subplots()
for i in range(1, 6):
    ax.plot(x, i*x + x, label='$y={i}x + {i}$'.format(i=i))
ax.legend(loc='upper left')
plt.show()

And this generated code:

import matplotlib.pyplot as plt1
import numpy as np

x = np.linspace(0, 10, 100)

fig, ax = plt1.subplots()
ax.legend(loc='upper left')
for i in range(1, 6):
    ax.plot(x, i*x + x, label='$y={i}x + {i}$'.format(i=i))
plt1.show()

Both code give the same plot with one swapping line, i would like to test something like:

plt == plt1
>> True
